报告摘要:Integrable systems were studied already in the late 1800s and their active development started again after the seminal paper of Zabusky and Kruskal in 1965. In this paper they demonstrated elastic scattering in the Korteweg-de Vries equation and coined the term "soliton".  Subsequently many interesting mathematical properties of integrable systems were revealed, along with practical applications. I will present three different classes of equations and corresponding definitions of integrability specially suited for them. Finally I will demonstrate that even though different classes of integrable systems were originally defined by different criteria, there are in fact various connections between them.
