Speaker: Joseph Krasil'shchik

Title: On integrable structures on the Hirota equation

Abstract:
The Hirota equation is obtained by covering the KdV one using the differential substitution . This is a fourth-order non-evolution equation of a rather complicated form, (see the ref.). I shall describe how quite simple computations lead to description of Hamiltonian, simplectic, and recursion operators for this equation.

This is a join work with Paul Kersten and Alexander Verbovetsky.
