题目：KAM Theorem for Hamiltonian with Sublinear Growth Frequencies at Infinity

报告人：徐新冬 （东南大学 ）

摘要：We prove an infinite-dimensional KAM theorem for a Hamiltonian system with sublinear growth frequencies at infinity. The main purpose is to present a new and simple method to study the dynamics of such Hamiltonian. We will outline the main difficulty due to sublinear growth frequencies and then present the method to overcome this problem. We apply this theorem to a fractional nonlinear Schrödinger equation on the torus T, thus proving existence and stability of quasi–periodic solutions.
