                Abstract:

                In this talk, I will present the numerical methods for solving the nonlinear Klein-Gordon equation and some related models in the highly oscillatory regime. I will start with my work for the nonlinear Klein-Gordon equation in the non-relativistic limit regime, and introduce the uniformly accurate (UA) method. The UA method can allow step size independent of the small parameter. Then I will present my recent work of designing such UA scheme for the Klein-Gordon-Zakharov system in a double limit regime, which is an important model in plasma physics involving two independent small parameters.
