Long time stability for quasi-periodic forced nonlinear Schrödinger equation
Shengqing Hu, Jing ZhangIn this paper, we firstly obtain a Birkhoff normal form theorem for a non-autonomous Hamiltonian system. Based on this result, we investigate the subexponential long time stability of equilibrium for quasi-periodic forced nonlinear Schrödinger equation in a Gevrey space.
