In [[number theory]], an '''algebraic integer''' is a [[complex number]] that is a [[root of a function|root]] of some [[monic polynomial]] (a polynomial whose leading coefficient is 1) with coefficients in {{math|ℤ}} (the set of [[integer]]s). The set of all algebraic integers is closed under addition and multiplication and therefore is a [[subring]] of complex numbers denoted by '''A'''. The ring '''A''' is the [[integral closure]] of regular integers {{math|ℤ}} in complex numbers. | |||
The [[ring of integers]] of a [[number field]] ''K'', denoted by ''O<sub>K</sub>'', is the intersection of ''K'' and '''A''': it can also be characterised as the maximal [[Order (ring theory)|order]] of the field ''K''. | |||
Each algebraic integer belongs to the ring of integers of some number field. A number ''x'' is an algebraic integer [[if and only if]] the ring {{math|ℤ}}[''x''] is [[Finitely generated group|finitely generated]] as an [[abelian group]], which is to say, as a [[Free Z-module|{{math|ℤ}}-module]]. | |||
==Definitions== | |||
The following are equivalent definitions of an algebraic integer. Let ''K'' be a [[number field]] (i.e., a [[finite extension]] of <math>\mathbb Q</math>, the set of [[rational number]]s), in other words, <math>K = \mathbb{Q}(\theta)</math> for some algebraic number <math>\theta \in \mathbb{C}</math> by the [[primitive element theorem]]. | |||
* <math>\alpha \in K</math> is an algebraic integer if there exists a monic polynomial <math>f(x) \in \mathbb{Z}[x]</math> such that <math>f(\alpha) = 0</math>. | |||
* <math>\alpha \in K</math> is an algebraic integer if the minimal monic polynomial of <math>\alpha</math> over <math>\mathbb Q</math> is in <math>\mathbb{Z}[x]</math>. | |||
* <math>\alpha \in K</math> is an algebraic integer if <math>\mathbb{Z}[\alpha]</math> is a finitely generated <math>\mathbb Z</math>-module. | |||
* <math>\alpha \in K </math> is an algebraic integer if there exists a finitely generated <math>\mathbb{Z}</math>-submodule <math>M \subset \mathbb{C}</math> such that <math>\alpha M \subseteq M</math>. | |||
Algebraic integers are a special case of [[integral element]]s of a ring extension. In particular, an algebraic integer is an integral element of a finite extension <math>K / \mathbb{Q}</math>. | |||
==Examples== | |||
* The only algebraic integers which are found in the set of [[rational numbers]] are the integers. In other words, the intersection of '''Q''' and '''A''' is exactly '''Z'''. The rational number ''a''/''b'' is not an algebraic integer unless ''b'' divides ''a''. Note that the leading coefficient of the polynomial ''bx'' − ''a'' is the integer ''b''. As another special case, the square root √''n'' of a non-negative integer ''n'' is an algebraic integer, and so is irrational unless ''n'' is a [[square number|perfect square]]. | |||
*If ''d'' is a [[square free]] integer then the extension ''K'' = '''Q'''(√{{overline|''d''}}) is a [[quadratic field extension|quadratic field]] of rational numbers. The ring of algebraic integers ''O<sub>K</sub>'' contains √{{overline|''d''}} since this is a root of the monic polynomial ''x''<sup>2</sup> − ''d''. Moreover, if ''d'' ≡ 1 (mod 4) the element (1 + √{{overline|''d''}})/2 is also an algebraic integer. It satisfies the polynomial ''x''<sup>2</sup> − ''x'' + (1 − ''d'')/4 where the [[constant term]] (1 − ''d'')/4 is an integer. The full ring of integers is generated by √{{overline|''d''}} or (1 + √{{overline|''d''}})/2 respectively. See [[quadratic integer]]s for more. | |||
*The ring of integers of the field <math>F = \mathbf Q[\alpha], \alpha = \sqrt[3] m </math> has the following [[integral basis]], writing <math>m = hk^2</math> for two square-free coprime integers ''h'' and ''k'':<ref>{{Citation | last1=Marcus | first1=Daniel A. | title=Number fields | publisher=[[Springer-Verlag]] | location=Berlin, New York | isbn=978-0-387-90279-1 | year=1977}}, chapter 2, p. 38 and exercise 41.</ref> | |||
:<math>\begin{cases} | |||
1, \alpha, \frac{\alpha^2 \pm k^2 \alpha + k^2}{3k} & m \equiv \pm 1 \mod 9 \\ | |||
1, \alpha, \frac{\alpha^2}k & \mathrm{else} | |||
\end{cases}</math> | |||
* If ''ζ<sub>n</sub>'' is a primitive ''n''-th [[root of unity]], then the ring of integers of the [[cyclotomic field]] '''Q'''(''ζ<sub>n</sub>'') is precisely '''Z'''[''ζ<sub>n</sub>'']. | |||
* If ''α'' is an algebraic integer then <math>\beta=\sqrt[n]{\alpha}</math> is another algebraic integer. A polynomial for ''β'' is obtained by substituting ''x''<sup>''n''</sup> in the polynomial for ''α''. | |||
==Non-example== | |||
* If ''P''(''x'') is a [[Primitive polynomial (ring theory)|primitive polynomial]] which has integer coefficients but is not monic, and ''P'' is [[irreducible polynomial|irreducible]] over '''Q''', then none of the roots of ''P'' are algebraic integers. (Here ''primitive'' is used in the sense that the [[highest common factor]] of the set of coefficients of ''P'' is 1; this is weaker than requiring the coefficients to be pairwise relatively prime.) | |||
==Facts== | |||
* The sum, difference and product of two algebraic integers is an algebraic integer. In general their quotient is not. The monic polynomial involved is generally of higher [[degree of a polynomial|degree]] than those of the original algebraic integers, and can be found by taking resultants and factoring. For example, if ''x''<sup>2</sup> − ''x'' − 1 = 0, ''y''<sup>3</sup> − ''y'' − 1 = 0 and ''z'' = ''xy'', then eliminating ''x'' and ''y'' from ''z'' − ''xy'' and the polynomials satisfied by ''x'' and ''y'' using the [[resultant]] gives ''z''<sup>6</sup> − 3''z''<sup>4</sup> − 4''z''<sup>3</sup> + ''z''<sup>2</sup> + ''z'' − 1, which is irreducible, and is the monic polynomial satisfied by the product. (To see that the ''xy'' is a root of the x-resultant of ''z'' − ''xy'' and ''x''<sup>2</sup> − ''x'' − 1, one might use the fact that the resultant is contained in the ideal generated by its two input polynomials.) | |||
* Any number constructible out of the integers with roots, addition, and multiplication is therefore an algebraic integer; but not all algebraic integers are so constructible: in a naïve sense, most roots of irreducible [[quintic]]s are not. This is the [[Abel-Ruffini theorem]]. <!-- what is the meaning of "most" roots of irreducible quintics? By counting, there are as many non-solvable as solvable quintics. Are coefficients of the quintic taken "randomly" from the integers? There ain't no such "random" integer! //--><!--How about this: Consider irreducible quintics of degree n, with integer coefficients with absolute value <= a. Does the proportion of them that are solvable not approach 0 as n and a go to infinitely, whether separately or together?--> | |||
* Every root of a monic polynomial whose coefficients are algebraic integers is itself an algebraic integer. In other words, the algebraic integers form a ring which is [[integrally closed]] in any of its extensions. | |||
* The ring of algebraic integers '''A''' is a [[Bézout domain]]. | |||

Algebraic integers are a special case of integral elements of a ring extension. In particular, an algebraic integer is an integral element of a finite extension .
Examples
- The only algebraic integers which are found in the set of rational numbers are the integers. In other words, the intersection of Q and A is exactly Z. The rational number a/b is not an algebraic integer unless b divides a. Note that the leading coefficient of the polynomial bx − a is the integer b. As another special case, the square root √n of a non-negative integer n is an algebraic integer, and so is irrational unless n is a perfect square.
- If d is a square free integer then the extension K = Q(√Template:Overline) is a quadratic field of rational numbers. The ring of algebraic integers OK contains √Template:Overline since this is a root of the monic polynomial x2 − d. Moreover, if d ≡ 1 (mod 4) the element (1 + √Template:Overline)/2 is also an algebraic integer. It satisfies the polynomial x2 − x + (1 − d)/4 where the constant term (1 − d)/4 is an integer. The full ring of integers is generated by √Template:Overline or (1 + √Template:Overline)/2 respectively. See quadratic integers for more.
- The ring of integers of the field has the following integral basis, writing for two square-free coprime integers h and k:[1]
![{\displaystyle F=\mathbf {Q} [\alpha ],\alpha ={\sqrt[{3}]{m}}}](https://wikimedia.org/api/rest_v1/media/math/render/svg/72907c7a2c5d2bea3d6ab81c37b75a613bcde659)
- If ζn is a primitive n-th root of unity, then the ring of integers of the cyclotomic field Q(ζn) is precisely Z[ζn].
- If α is an algebraic integer then is another algebraic integer. A polynomial for β is obtained by substituting xn in the polynomial for α.
![{\displaystyle \beta ={\sqrt[{n}]{\alpha }}}](https://wikimedia.org/api/rest_v1/media/math/render/svg/1b4ea61cb6b4d43ac50807dd3b44822dad2c9ab0)
Non-example
- If P(x) is a primitive polynomial which has integer coefficients but is not monic, and P is irreducible over Q, then none of the roots of P are algebraic integers. (Here primitive is used in the sense that the highest common factor of the set of coefficients of P is 1; this is weaker than requiring the coefficients to be pairwise relatively prime.)
Facts
- The sum, difference and product of two algebraic integers is an algebraic integer. In general their quotient is not. The monic polynomial involved is generally of higher degree than those of the original algebraic integers, and can be found by taking resultants and factoring. For example, if x2 − x − 1 = 0, y3 − y − 1 = 0 and z = xy, then eliminating x and y from z − xy and the polynomials satisfied by x and y using the resultant gives z6 − 3z4 − 4z3 + z2 + z − 1, which is irreducible, and is the monic polynomial satisfied by the product. (To see that the xy is a root of the x-resultant of z − xy and x2 − x − 1, one might use the fact that the resultant is contained in the ideal generated by its two input polynomials.)
- Any number constructible out of the integers with roots, addition, and multiplication is therefore an algebraic integer; but not all algebraic integers are so constructible: in a naïve sense, most roots of irreducible quintics are not. This is the Abel-Ruffini theorem.
- Every root of a monic polynomial whose coefficients are algebraic integers is itself an algebraic integer. In other words, the algebraic integers form a ring which is integrally closed in any of its extensions.
- The ring of algebraic integers A is a Bézout domain.

In case you are in search of an actual estate or Singapore property agent on-line, you simply should belief your intuition. It's because you do not know which agent is nice and which agent will not be. Carry out research on several brokers by looking out the internet. As soon as if you end up positive that a selected agent is dependable and reliable, you can choose to utilize his partnerise in finding you a home in Singapore. Most of the time, a property agent is taken into account to be good if he or she locations the contact data on his website. This may mean that the agent does not mind you calling them and asking them any questions relating to new properties in singapore in Singapore.
