Two Poisson structures invariant with respect to discrete transformation in the case of arbitrary semi-simple algebras
arXiv:0801.2541
Abstract
Two Poisson structures invariant with respect to discrete transformation of the Maximal root in the case of arbitrary semi-simple algebras are presented in explicit form. Thus the problem of construction of equations of n-wave hierarchy in the case of arbitrary semi simple algebra is solved finally.
