Integrable model
Integrable model In theoretical physics, an integrable model is a model, a theory or ... of elementary (or special) functions; the adjective integrable is therefore equivalent to "solvable". By a ... set of correlation functions. Many models are integrable because of an enhanced symmetry, for example ... particles as functions of the moduli space. Integrable models have infinitely many conserved charges .
