报告题目：Analysis of fully discrete approximations for dissipative systems and its applications
报告摘要：In this talk, we consider time discretization methods for general dissipative systems. We introduce a class of implicit Runge-Kutta methods which satisfy two conditions. Under these two conditions with the dissipative condition, we can obtain the energy boundedness and a priori error estimates. Then we consider a specific dissipative system, with the discontinuous Galerkin discretization in space for the time-dependent nonlocal diffusion problems. It is very convenient to obtain the theoretical results by verifying several conditions. Some numerical experiments are given to validate our analysis.
