In [[theoretical physics]] '''Pohlmeyer charge''', named for [[:de:Klaus Pohlmeyer|Klaus Pohlmeyer]], is a conserved [[Charge invariance|charge invariant]] under the [[Virasoro algebra]] or its generalization. It can be obtained by expanding the [[holonomy|holonomies]] (generating functions)
 
:<math>P\,Tr\, \exp i T_\mu\oint d\sigma A_\sigma^{(\mu)}(\sigma)</math>
 
with respect to the constant matrices ''T''. The gauge field <math>A_\sigma^\mu</math> is defined as a combination of <math>\partial X^\mu</math> and its conjugate.
 
According to the logic of [[loop quantum gravity]] and [[algebraic quantum field theory]], these charges are the right physical quantities that should be used for quantization. This logic is however incompatible with the standard and well-established methods of [[quantum field theory]] based on [[Fock space]] and [[perturbation theory]].

I would like to introduce myself to you, I am Andrew and my spouse doesn't like it at all. To climb is some thing she would never give up. My wife and I live in Mississippi and I adore each working day living here. Invoicing is my occupation.
