报告摘要
In this talk, we study two-dimensional point vortex system under analytic quasi-periodic perturbations, which describe the particle advection around a fixed vortex in a two-dimensional ideal fluid under the action of a quasi-periodic background flow. We first prove the singularity (0,0) is stable and then give the sufficient conditions of the existence of response solutions when the perturbation only relies on time t.
