报告摘要：Integrable systems belong to an exceptional class of nonlinear equations, which can be studied with the same completeness as linear systems, at least in principle. They possess a rich set of exact solutions and many hidden properties. Classification of integrable equations is a central problem. There are many approaches to this problem, among which the symmetry approach has proved to be very efficient and powerful. In this talk, I'll give a brief account of recent development of the symmetry approach. The progress has been achieved mainly due to a symbolic representation of the ring of differential polynomials, which enables us to use results from algebraic geometry and number theory.
