Place : Seminar Room 617, Institute of Mathematics (NTU Campus)
Abstract: Hirota difference equation is widely known not only because of its integrability, but as equation that generates many other integrable ones. We present higher analogs of this 2+1 dimensional equation, consider its limiting cases that reduce to partial differential-difference and differential integrable equations. Different kinds of 1+1 dimensional reductions are considered as well. Presentation is based on relation of integrability with commutator identities on associative algebras.
