报告题目： Approximate symmetry approach for differential-difference equations
报告摘要：In this talk, I will discuss the recent development on approximate symmetry approach for differential-difference equations. It enables us to produce necessary integrability conditions, to determine whether a given equation is integrable or not, and to advance in classification of integrable equations. We apply the developed formalism to solve the classification problem of integrable equations for anti-symmetric quasi-linear equations of order (−3, 3) and produce a list of 17 equations satisfying the necessary integrability conditions. For every equation from the list, we present an infinite family of integrable higher order relatives. Some of the equations obtained are new. This is a joint work with A.V. Mikhailov and V.S. Novikov recently published on Commun. Math. Phys. .
