Hirota difference equation and a commutator identity on an associative algebra
A. K. Pogrebkov
Steklov Mathematical Institute, Moscow, Russia
In earlier papers of the author it was shown that some simple commutator identities on an associative algebra generate integrable nonlinear equations. Here, this observation is generalized to the case of difference nonlinear equations. The identity under study leads, under a special realization of the elements of the associative algebra, to the famous Hirota difference equation. Direct and inverse problems are considered for this equation, as well as some properties of its solutions. Finally, some other commutator identities are discussed and their relationship with integrable nonlinear equations, both differential and difference, is demonstrated.
Hirota difference equation, commutator identity, extended operators, direct and inverse problems.
