In [[mathematics]], the '''Freudenthal magic square''' (or '''Freudenthal–Tits magic square''') is a construction relating several [[Lie algebra]]s (and their associated [[Lie group]]s). It is named after [[Hans Freudenthal]] and [[Jacques Tits]], who developed the idea independently. It associates a Lie algebra to a pair of division algebras ''A'', ''B''. The resulting Lie algebras have [[Dynkin diagram]]s according to the table at right. The "magic" of the Freudenthal magic square is that the constructed Lie algebra is symmetric in ''A'' and ''B'', despite the original construction not being symmetric, though [[#Vinberg's symmetric method|Vinberg's symmetric method]] gives a symmetric construction; it is not a [[magic square]] as in [[recreational mathematics]]. | |||
The Freudenthal magic square includes all of the [[exceptional Lie group]]s apart from ''G''<sub>2</sub>, and it provides one possible approach to justify the assertion that "the exceptional Lie groups all exist because of the [[octonions]]": ''G''<sub>2</sub> itself is the [[automorphism group]] of the octonions (also, it is in many ways like a [[classical Lie group]] because it is the stabilizer of a generic 3-form on a 7-dimensional vector space – see [[prehomogeneous vector space]]). | |||
==Constructions== | |||
See [[#History|history]] for context and motivation. These were originally constructed circa 1958 by Freudenthal and Tits, with more elegant formulations following in later years.<ref name="baez200243" /> | |||
== | ===Tits' approach=== | ||
Tits' approach, discovered circa 1958 and published in {{Harv|Tits|1966}}, is as follows. | |||
Associated with any normed real [[division algebra]] ''A'' (i.e., R, C, H or O) there is a [[Jordan algebra]], ''J''<sub>3</sub>(''A''), of 3 × 3 ''A''-[[Hermitian matrices]]. For any pair (''A'', ''B'') of such division algebras, one can define a [[Lie algebra]] | |||
:<math> L=\left (\mathfrak{der}(A)\oplus\mathfrak{der}(J_3(B))\right )\oplus \left (A_0\otimes J_3(B)_0 \right )</math> | |||
where ''der'' denotes the Lie algebra of [[derivation (abstract algebra)|derivation]]s of an algebra, and the subscript 0 denotes the [[trace-free]] part. The Lie algebra ''L'' has <math>\mathfrak{der}(A)\oplus\mathfrak{der}(J_3(B))</math> as a subalgebra, and this acts naturally on <math>A_0\otimes J_3(B)_0</math>. The Lie bracket on <math>A_0\otimes J_3(B)_0</math> (which is not a subalgebra) is not obvious, but Tits showed how it could be defined, and that it produced the following table of [[compact Lie algebra]]s. | |||

| <math>\mathfrak{e}_8</math> | |||
|} | |||
Note that by construction, the row of the table with ''A''='''R''' gives '''der'''(J<sub>3</sub>(''B'')), and similarly vice versa. | |||
===Vinberg's symmetric method=== | |||
The "magic" of the Freudenthal magic square is that the constructed Lie algebra is symmetric in ''A'' and ''B''. This is not obvious from Tits' construction. [[Ernest Vinberg]] gave a construction which is manifestly symmetric, in {{Harv|Vinberg|1966}}. Instead of using a Jordan algebra, he uses an algebra of skew-hermitian trace-free matrices with entries in ''A'' ⊗ ''B'', denoted <math>\mathfrak{sa}_3(A\otimes B)</math>. Vinberg defines a Lie algebra structure on | |||
:<math> \mathfrak{der}(A)\oplus\mathfrak{der}(B)\oplus\mathfrak{sa}_3(A\otimes B).</math> | |||
When ''A'' and ''B'' have no derivations (i.e., '''R''' or '''C'''), this is just the Lie (commutator) bracket on <math>\mathfrak{sa}_3(A\otimes B)</math>. In the presence of derivations, these form a subalgebra acting naturally on <math>\mathfrak{sa}_3(A\otimes B)</math> as in Tits' construction, and the tracefree commutator bracket on <math>\mathfrak{sa}_3(A\otimes B)</math> is modified by an expression with values in <math> \mathfrak{der}(A)\oplus\mathfrak{der}(B)</math>. | |||
===Triality=== | |||
A more recent construction, due to [[Pierre Ramond]] {{Harv|Ramond|1976}} and Bruce Allison {{Harv|Allison|1978}} and developed by Chris Barton and [[Tony Sudbery|Anthony Sudbery]], uses [[triality]] in the form developed by [[John Frank Adams]]; this was presented in {{Harv|Barton|Sudbery|2000}}, and in streamlined form in {{Harv|Barton|Sudbery|2003}}. Whereas Vinberg's construction is based on the automorphism groups of a division algebra ''A'' (or rather their Lie algebras of derivations), Barton and Sudbery use the group of automorphisms of the corresponding triality. The triality is the trilinear map | |||
:<math> A_1\times A_2\times A_3 \to \mathbf R</math> | |||
obtained by taking three copies of the division algebra ''A'', and using the inner product on ''A'' to dualize the multiplication. The automorphism group is the subgroup of SO(''A''<sub>1</sub>) × SO(''A''<sub>2</sub>) × SO(''A''<sub>3</sub>) preserving this trilinear map. It is denoted Tri(''A''). The following table compares its Lie algebra to the Lie algebra of derivations. | |||
{| class="wikitable" | |||

| <math>\mathfrak{sp}_1 \oplus \mathfrak{sp}_1\oplus \mathfrak{sp}_1</math> | |||
| <math>\mathfrak{so}_8</math> | |||
|} | |||
Barton and Sudbery then identify the magic square Lie algebra corresponding to (''A'',''B'') with a Lie algebra structure on the vector space | |||
:<math> \mathfrak{tri}(A)\oplus\mathfrak{tri}(B)\oplus (A_1\otimes B_1)\oplus (A_2\otimes B_2)\oplus (A_3\otimes B_3). </math> | |||
The Lie bracket is compatible with a '''Z'''<sub>2</sub> × '''Z'''<sub>2</sub> grading, with '''tri'''(''A'') and '''tri'''(''B'') in degree (0,0), and the three copies of ''A'' ⊗ ''B'' in degrees (0,1), (1,0) and (1,1). The bracket preserves '''tri'''(''A'') and '''tri'''(''B'') and these act naturally on the three copies of ''A'' ⊗ ''B'', as in the other constructions, but the brackets between these three copies are more constrained. | |||
For instance when ''A'' and ''B'' are the octonions, the triality is that of Spin(8), the double cover of SO(8), and the Barton-Sudbery description yields | |||
:<math>\mathfrak e_8\cong \mathfrak{so}_8\oplus\widehat{\mathfrak{so}}_8\oplus(V\otimes \widehat V)\oplus (S_+\otimes\widehat S_+)\oplus (S_-\otimes \widehat S_-)</math> | |||
where V, S<sub>+</sub> and S<sub>-</sub> are the three 8 dimensional representations of <math>\mathfrak{so}_8</math> (the fundamental representation and the two [[spin representation]]s), and the hatted objects are an isomorphic copy. | |||
With respect to one of the '''Z'''<sub>2</sub> gradings, the first three summands combine to give <math>\mathfrak{so}_{16}</math> and the last two together form one of its spin representations Δ<sub>+</sub><sup>128</sup> (the superscript denotes the dimension). This is a well known [[Riemannian symmetric space|symmetric decomposition]] of [[E8 (mathematics)|E8]]. | |||
The Barton-Sudbery construction extends this to the other Lie algebras in the magic square. In particular, for the exceptional Lie algebras in the last row (or column), the symmetric decompositions are: | |||
:<math>\mathfrak f_4\cong \mathfrak{so}_9\oplus \Delta^{16}</math> | |||
:<math>\mathfrak e_6\cong (\mathfrak{so}_{10}\oplus \mathfrak u_1)\oplus \Delta^{32}</math> | |||
:<math>\mathfrak e_7\cong (\mathfrak{so}_{12}\oplus \mathfrak{sp}_1)\oplus \Delta_+^{64}</math> | |||
:<math>\mathfrak e_8\cong \mathfrak{so}_{16}\oplus \Delta_+^{128}.</math> | |||
==Generalizations== | |||
===Split composition algebras=== | |||
In addition to the [[normed division algebra]]s, there are other [[composition algebra]]s over '''R''', namely the [[split-complex number]]s, the [[split-quaternions]] and the [[split-octonions]]. If one uses these instead of the complex numbers, quaternions, and octonions, one obtains the following variant of the magic square (where the split versions of the division algebras are denoted by a dash). | |||

|} | |||
Here all the Lie algebras are the [[List of simple Lie groups|split real form]] except for '''so'''<sub>3</sub>, but a sign change in the definition of the Lie bracket can be used to produce the split form '''so'''<sub>2,1</sub>. In particular, for the exceptional Lie algebras, the maximal compact subalgebras are as follows: | |||
{| class="wikitable" | |||
|- | |||
! Split form | |||
| <math>\mathfrak{f}_{4(4)}</math> | |||
| <math>\mathfrak{e}_{6(6)}</math> | |||

| <math>\mathfrak{sp}_4</math> | |||
| <math>\mathfrak{su}_8</math> | |||
| <math>\mathfrak{so}_{16}</math> | |||
|} | |||
A non-symmetric version of the magic square can also be obtained by combining the split algebras with the usual division algebras. According to Barton and Sudbery, the resulting table of Lie algebras is as follows. | |||

|} | |||
===Arbitrary fields=== | |||
The split forms of the composition algebras and Lie algebras can be defined over any [[field (mathematics)|field]] '''K'''. This yields the following magic square. | |||
{| class="wikitable" | |||
|- | |||
|<math>\mathfrak{so}_3(\mathbf K)</math> | |||
|<math>\mathfrak{sl}_3(\mathbf K)</math> | |||
|<math>\mathfrak{sp}_6(\mathbf K)</math> | |||
|<math>\mathfrak{f}_{4}(\mathbf K)</math> | |||
|- | |||
|<math>\mathfrak{sl}_3(\mathbf K)</math> | |||
|<math>\mathfrak{sl}_3(\mathbf K)\oplus\mathfrak{sl}_3(\mathbf K)</math> | |||
|<math>\mathfrak{sl}_6(\mathbf K)</math> | |||
|<math>\mathfrak{e}_{6}(\mathbf K)</math> | |||
|- | |||
| <math>\mathfrak{sp}_6(\mathbf K)</math> | |||
| <math>\mathfrak{sl}_6(\mathbf K)</math> | |||
| <math>\mathfrak{so}_{12}(\mathbf K)</math> | |||
| <math>\mathfrak{e}_{7}(\mathbf K)</math> | |||
|- | |||
| <math>\mathfrak{f}_{4}(\mathbf K)</math> | |||
| <math>\mathfrak{e}_{6}(\mathbf K)</math> | |||
| <math>\mathfrak{e}_{7}(\mathbf K)</math> | |||
| <math>\mathfrak{e}_{8}(\mathbf K)</math> | |||
|} | |||
There is some ambiguity here if '''K''' is not algebraically closed. In the case '''K''' = '''C''', this is the complexification of the Freudenthal magic squares for '''R''' discussed so far. | |||
===More general Jordan algebras=== | |||
The squares discussed so far are related to the Jordan algebras ''J''<sub>3</sub>(''A''), where ''A'' is a division algebra. There are also Jordan algebras ''J<sub>n</sub>''(''A''), for any positive integer ''n'', as long as ''A'' is associative. These yield split forms (over any field '''K''') and compact forms (over '''R''') of generalized magic squares. | |||

| <math>\mathfrak{so}_{4n}(\mathbf K)</math> | |||
|} | |||
For ''n''=2, J<sub>''2''</sub>(''O'') is also a Jordan algebra. In the compact case (over '''R''') this yields a magic square of orthogonal Lie algebras. | |||

The last row and column here are the orthogonal algebra part of the isotropy algebra in the symmetric decomposition of the exceptional Lie algebras mentioned previously. | |||
These constructions are closely related to [[hermitian symmetric space]]s – cf. [[prehomogeneous vector space]]s. | |||
===Symmetric spaces=== | |||
[[Riemannian symmetric space]]s, both compact and non-compact, can be classified uniformly using a magic square construction, in {{Harv|Huang|Leung|2011}}. The irreducible compact symmetric spaces are, up to finite covers, either a compact simple Lie group, a Grassmannian, a [[Lagrangian Grassmannian]], or a [[double Lagrangian Grassmannian]] of subspaces of <math>(\mathbf A \otimes \mathbf B)^n,</math> for normed division algebras '''A''' and '''B'''. A similar construction produces the irreducible non-compact symmetric spaces. | |||
==History== | |||
===Rosenfeld projective planes=== | |||
Following [[Ruth Moufang]]'s discovery in 1933 of the [[Cayley projective plane]] or "octonionic projective plane" '''P'''<sup>2</sup>('''O'''), whose symmetry group is the exceptional Lie group [[F4 (mathematics)|F<sub>4</sub>]], and with the knowledge that [[G2 (mathematics)|''G''<sub>2</sub>]] is the automorphism group of the octonions, it was proposed by {{harvtxt|Rozenfeld|1956}} that the remaining exceptional Lie groups [[E6 (mathematics)|''E''<sub>6</sub>]], [[E7 (mathematics)|''E''<sub>7</sub>]], and [[E8 (mathematics)|E<sub>8</sub>]] are isomorphism groups of projective planes over certain algebras over the octonions:<ref name="baez200243">{{Harv|Baez|2002|loc=[http://math.ucr.edu/home/baez/octonions/node16.html 4.3 The Magic Square]}}</ref> | |||
* the '''{{visible anchor|bioctonions}}''', '''C''' ⊗ '''O''', | |||
* the '''{{visible anchor|quateroctonions}}''', '''H''' ⊗ '''O''', | |||
* the '''{{visible anchor|octooctonions}}''', '''O''' ⊗ '''O'''. | |||
This proposal is appealing, as there are certain exceptional compact [[Riemannian symmetric space]]s with the desired symmetry groups and whose dimension agree with that of the putative projective planes (dim('''P'''<sup>2</sup>('''K''' ⊗ '''K'''′)) = 2dim('''K''')dim('''K'''′)), and this would give a uniform construction of the exceptional Lie groups as symmetries of naturally occurring objects (i.e., without an a priori knowledge of the exceptional Lie groups). The Riemannian symmetric spaces were classified by Cartan in 1926 (Cartan's labels are used in sequel); see [[Riemannian symmetric space#Classification of Riemannian symmetric spaces|classification]] for details, and the relevant spaces are: | |||
* the [[octonionic projective plane]] – FII, dimension 16 = 2 × 8, F<sub>4</sub> symmetry, [[Cayley projective plane]] '''P'''<sup>2</sup>('''O'''), | |||
* the bioctonionic projective plane – EIII, dimension 32 = 2 × 2 × 8, E<sub>6</sub> symmetry, complexified Cayley projective plane, '''P'''<sup>2</sup>('''C''' ⊗ '''O'''), | |||
* the "'''{{visible anchor|quateroctonionic projective plane}}'''"<ref name="baez200245">{{Harv|Baez|2002|loc=[http://math.ucr.edu/home/baez/octonions/node18.html 4.5 '''E'''<sub>7</sub>]}}</ref> – EVI, dimension 64 = 2 × 4 × 8, E<sub>7</sub> symmetry, '''P'''<sup>2</sup>('''H''' ⊗ '''O'''), | |||
* the "'''{{visible anchor|octooctonionic projective plane}}'''"<ref name="baez200246">{{Harv|Baez|2002|loc= [http://math.ucr.edu/home/baez/octonions/node19.html 4.6 '''E'''<sub>8</sub>]}}</ref> – EVIII, dimension 128 = 2 × 8 × 8, E<sub>8</sub> symmetry, '''P'''<sup>2</sup>('''O''' ⊗ '''O'''). | |||
The difficulty with this proposal is that while the octonions are a division algebra, and thus a projective plane is defined over them, the bioctonions, quateroctonions and octooctonions are not division algebras, and thus the usual definition of a projective plane does not work. This can be resolved for the bioctonions, with the resulting projective plane being the complexified Cayley plane, but the constructions do not work for the quateroctonions and octooctonions, and the spaces in question do not obey the usual axioms of projective planes,<ref name="baez200243" /> hence the quotes on "(putative) projective plane". However, the tangent space at each point of these spaces can be identified with the plane ('''H''' ⊗ '''O''')<sup>2</sup>, or ('''O''' ⊗ '''O''')<sup>2</sup> further justifying the intuition that these are a form of generalized projective plane.<ref name="baez200245" /><ref name="baez200246" /> Accordingly, the resulting spaces are sometimes called '''Rosenfeld projective planes''' and notated as if they were projective planes. More broadly, these compact forms are the '''Rosenfeld elliptic projective planes''', while the dual non-compact forms are the '''Rosenfeld hyperbolic projective planes'''. A more modern presentation of Rosenfeld's ideas is in {{Harv|Rosenfeld|1997}}, while a brief note on these "planes" is in {{Harv|Besse|1987|loc=pp. 313–316}}.<ref>"[http://math.ucr.edu/home/baez/twf_ascii/week106 This Week's Finds in Mathematical Physics - Week 106]", [[John Baez]] July 23, 1997</ref> | |||
The spaces can be constructed using Tit's theory of buildings, which allows one to construct a geometry with any given algebraic group as symmetries, but this requires starting with the Lie groups and constructing a geometry from them, rather than constructing a geometry independently of a knowledge of the Lie groups.<ref name="baez200243" /> | |||
===Magic square=== | |||
While at the level of manifolds and Lie groups, the construction of the projective plane '''P'''<sup>2</sup>('''K''' ⊗ '''K'''′) of two normed division algebras does not work, the corresponding construction at the level of Lie algebras ''does'' work. That is, if one decomposes the Lie algebra of infinitesimal isometries of the projective plane '''P'''<sup>2</sup>('''K''') and applies the same analysis to '''P'''<sup>2</sup>('''K''' ⊗ '''K'''′), one can use this decomposition, which holds when '''P'''<sup>2</sup>('''K''' ⊗ '''K'''′) can actually be defined as a projective plane, as a ''definition'' of a "magic square Lie algebra" ''M''('''K''','''K'''′) This definition is purely algebraic, and holds even without assuming the existence of the corresponding geometric space. This was done independently circa 1958 in {{Harv|Tits|1966}} and by Freudenthal in a series of 11 papers, starting with {{Harv|Freudenthal|1954}} and ending with {{Harv|Freudenthal|1963}}, though the simplified construction outlined here is due to {{Harv|Vinberg|1966}}.<ref name="baez200243" /> | |||

In mathematics, the Freudenthal magic square (or Freudenthal–Tits magic square) is a construction relating several Lie algebras (and their associated Lie groups). It is named after Hans Freudenthal and Jacques Tits, who developed the idea independently. It associates a Lie algebra to a pair of division algebras A, B. The resulting Lie algebras have Dynkin diagrams according to the table at right. The "magic" of the Freudenthal magic square is that the constructed Lie algebra is symmetric in A and B, despite the original construction not being symmetric, though Vinberg's symmetric method gives a symmetric construction; it is not a magic square as in recreational mathematics.
The Freudenthal magic square includes all of the exceptional Lie groups apart from G2, and it provides one possible approach to justify the assertion that "the exceptional Lie groups all exist because of the octonions": G2 itself is the automorphism group of the octonions (also, it is in many ways like a classical Lie group because it is the stabilizer of a generic 3-form on a 7-dimensional vector space – see prehomogeneous vector space).
Constructions
See history for context and motivation. These were originally constructed circa 1958 by Freudenthal and Tits, with more elegant formulations following in later years.[1]
Tits' approach
Tits' approach, discovered circa 1958 and published in Template:Harv, is as follows.
Associated with any normed real division algebra A (i.e., R, C, H or O) there is a Jordan algebra, J3(A), of 3 × 3 A-Hermitian matrices. For any pair (A, B) of such division algebras, one can define a Lie algebra
where der denotes the Lie algebra of derivations of an algebra, and the subscript 0 denotes the trace-free part. The Lie algebra L has as a subalgebra, and this acts naturally on . The Lie bracket on (which is not a subalgebra) is not obvious, but Tits showed how it could be defined, and that it produced the following table of compact Lie algebras.
B | R | C | H | O | |
---|---|---|---|---|---|
A | der(A/B) | 0 | 0 | ||
R | 0 | ||||
C | 0 | ||||
H | |||||
O |
Note that by construction, the row of the table with A=R gives der(J3(B)), and similarly vice versa.
Vinberg's symmetric method
The "magic" of the Freudenthal magic square is that the constructed Lie algebra is symmetric in A and B. This is not obvious from Tits' construction. Ernest Vinberg gave a construction which is manifestly symmetric, in Template:Harv. Instead of using a Jordan algebra, he uses an algebra of skew-hermitian trace-free matrices with entries in A ⊗ B, denoted . Vinberg defines a Lie algebra structure on
When A and B have no derivations (i.e., R or C), this is just the Lie (commutator) bracket on . In the presence of derivations, these form a subalgebra acting naturally on as in Tits' construction, and the tracefree commutator bracket on is modified by an expression with values in .
Triality
A more recent construction, due to Pierre Ramond Template:Harv and Bruce Allison Template:Harv and developed by Chris Barton and Anthony Sudbery, uses triality in the form developed by John Frank Adams; this was presented in Template:Harv, and in streamlined form in Template:Harv. Whereas Vinberg's construction is based on the automorphism groups of a division algebra A (or rather their Lie algebras of derivations), Barton and Sudbery use the group of automorphisms of the corresponding triality. The triality is the trilinear map
obtained by taking three copies of the division algebra A, and using the inner product on A to dualize the multiplication. The automorphism group is the subgroup of SO(A1) × SO(A2) × SO(A3) preserving this trilinear map. It is denoted Tri(A). The following table compares its Lie algebra to the Lie algebra of derivations.
A: | R | C | H | O |
---|---|---|---|---|
0 | 0 | |||
0 |
Barton and Sudbery then identify the magic square Lie algebra corresponding to (A,B) with a Lie algebra structure on the vector space
The Lie bracket is compatible with a Z2 × Z2 grading, with tri(A) and tri(B) in degree (0,0), and the three copies of A ⊗ B in degrees (0,1), (1,0) and (1,1). The bracket preserves tri(A) and tri(B) and these act naturally on the three copies of A ⊗ B, as in the other constructions, but the brackets between these three copies are more constrained.
For instance when A and B are the octonions, the triality is that of Spin(8), the double cover of SO(8), and the Barton-Sudbery description yields
where V, S+ and S- are the three 8 dimensional representations of (the fundamental representation and the two spin representations), and the hatted objects are an isomorphic copy.
With respect to one of the Z2 gradings, the first three summands combine to give and the last two together form one of its spin representations Δ+128 (the superscript denotes the dimension). This is a well known symmetric decomposition of E8.
The Barton-Sudbery construction extends this to the other Lie algebras in the magic square. In particular, for the exceptional Lie algebras in the last row (or column), the symmetric decompositions are:
Generalizations
Split composition algebras
In addition to the normed division algebras, there are other composition algebras over R, namely the split-complex numbers, the split-quaternions and the split-octonions. If one uses these instead of the complex numbers, quaternions, and octonions, one obtains the following variant of the magic square (where the split versions of the division algebras are denoted by a dash).
A\B | R | C' | H' | O' |
---|---|---|---|---|
R | ||||
C' | ||||
H' | ||||
O' |
Here all the Lie algebras are the split real form except for so3, but a sign change in the definition of the Lie bracket can be used to produce the split form so2,1. In particular, for the exceptional Lie algebras, the maximal compact subalgebras are as follows:
Split form | ||||
---|---|---|---|---|
Maximal compact |
A non-symmetric version of the magic square can also be obtained by combining the split algebras with the usual division algebras. According to Barton and Sudbery, the resulting table of Lie algebras is as follows.
A\B | R | C | H | O |
---|---|---|---|---|
R | ||||
C' | ||||
H' | ||||
O' |
The real exceptional Lie algebras appearing here can again be described by their maximal compact subalgebras.

---|---|---|---|---|---|
Maximal compact |
Arbitrary fields
The split forms of the composition algebras and Lie algebras can be defined over any field K. This yields the following magic square.
There is some ambiguity here if K is not algebraically closed. In the case K = C, this is the complexification of the Freudenthal magic squares for R discussed so far.
More general Jordan algebras
The squares discussed so far are related to the Jordan algebras J3(A), where A is a division algebra. There are also Jordan algebras Jn(A), for any positive integer n, as long as A is associative. These yield split forms (over any field K) and compact forms (over R) of generalized magic squares.
For n=2, J2(O) is also a Jordan algebra. In the compact case (over R) this yields a magic square of orthogonal Lie algebras.
A\B | R | C | H | O |
---|---|---|---|---|
R | ||||
C | ||||
H | ||||
O |
The last row and column here are the orthogonal algebra part of the isotropy algebra in the symmetric decomposition of the exceptional Lie algebras mentioned previously.
These constructions are closely related to hermitian symmetric spaces – cf. prehomogeneous vector spaces.
Symmetric spaces
Riemannian symmetric spaces, both compact and non-compact, can be classified uniformly using a magic square construction, in Template:Harv. The irreducible compact symmetric spaces are, up to finite covers, either a compact simple Lie group, a Grassmannian, a Lagrangian Grassmannian, or a double Lagrangian Grassmannian of subspaces of for normed division algebras A and B. A similar construction produces the irreducible non-compact symmetric spaces.
History
Rosenfeld projective planes
Following Ruth Moufang's discovery in 1933 of the Cayley projective plane or "octonionic projective plane" P2(O), whose symmetry group is the exceptional Lie group F4, and with the knowledge that G2 is the automorphism group of the octonions, it was proposed by Template:Harvtxt that the remaining exceptional Lie groups E6, E7, and E8 are isomorphism groups of projective planes over certain algebras over the octonions:[1]
- the Template:Visible anchor, C ⊗ O,
- the Template:Visible anchor, H ⊗ O,
- the Template:Visible anchor, O ⊗ O.
This proposal is appealing, as there are certain exceptional compact Riemannian symmetric spaces with the desired symmetry groups and whose dimension agree with that of the putative projective planes (dim(P2(K ⊗ K′)) = 2dim(K)dim(K′)), and this would give a uniform construction of the exceptional Lie groups as symmetries of naturally occurring objects (i.e., without an a priori knowledge of the exceptional Lie groups). The Riemannian symmetric spaces were classified by Cartan in 1926 (Cartan's labels are used in sequel); see classification for details, and the relevant spaces are:
- the octonionic projective plane – FII, dimension 16 = 2 × 8, F4 symmetry, Cayley projective plane P2(O),
- the bioctonionic projective plane – EIII, dimension 32 = 2 × 2 × 8, E6 symmetry, complexified Cayley projective plane, P2(C ⊗ O),
- the "Template:Visible anchor"[2] – EVI, dimension 64 = 2 × 4 × 8, E7 symmetry, P2(H ⊗ O),
- the "Template:Visible anchor"[3] – EVIII, dimension 128 = 2 × 8 × 8, E8 symmetry, P2(O ⊗ O).
The difficulty with this proposal is that while the octonions are a division algebra, and thus a projective plane is defined over them, the bioctonions, quateroctonions and octooctonions are not division algebras, and thus the usual definition of a projective plane does not work. This can be resolved for the bioctonions, with the resulting projective plane being the complexified Cayley plane, but the constructions do not work for the quateroctonions and octooctonions, and the spaces in question do not obey the usual axioms of projective planes,[1] hence the quotes on "(putative) projective plane". However, the tangent space at each point of these spaces can be identified with the plane (H ⊗ O)2, or (O ⊗ O)2 further justifying the intuition that these are a form of generalized projective plane.[2][3] Accordingly, the resulting spaces are sometimes called Rosenfeld projective planes and notated as if they were projective planes. More broadly, these compact forms are the Rosenfeld elliptic projective planes, while the dual non-compact forms are the Rosenfeld hyperbolic projective planes. A more modern presentation of Rosenfeld's ideas is in Template:Harv, while a brief note on these "planes" is in Template:Harv.[4]
The spaces can be constructed using Tit's theory of buildings, which allows one to construct a geometry with any given algebraic group as symmetries, but this requires starting with the Lie groups and constructing a geometry from them, rather than constructing a geometry independently of a knowledge of the Lie groups.[1]
Magic square
While at the level of manifolds and Lie groups, the construction of the projective plane P2(K ⊗ K′) of two normed division algebras does not work, the corresponding construction at the level of Lie algebras does work. That is, if one decomposes the Lie algebra of infinitesimal isometries of the projective plane P2(K) and applies the same analysis to P2(K ⊗ K′), one can use this decomposition, which holds when P2(K ⊗ K′) can actually be defined as a projective plane, as a definition of a "magic square Lie algebra" M(K,K′) This definition is purely algebraic, and holds even without assuming the existence of the corresponding geometric space. This was done independently circa 1958 in Template:Harv and by Freudenthal in a series of 11 papers, starting with Template:Harv and ending with Template:Harv, though the simplified construction outlined here is due to Template:Harv.[1]
