报告摘要:The major fact in the theory of dynamical systems is that structurally unstable maps can form open regions in the space of smooth maps. The simplest mechanism of destroying structural stability is a homoclinic tangency, i.e., a non-transverse intersection of the stable and unstable manifolds of a saddle periodic orbit. By the celebrated Newhouse Theorem, in the space of smooth maps there exist open regions (Newhouse domain) where maps with homoclinic tangencies are dense. Generically, maps from the Newhouse domain exhibit extremely complicated dynamics which includes coexistence of infinitely many sinks, superexponential growth of the number of periodic points, universal dynamics. In the lectures we will give an overview of classical results on the dynamics of maps from the Newhouse domain, as well as recent advances in this area.
欢迎广大师生届时参加!
