报告题目：Superconvergence Analysis of Discontinuous Galerkin time stepping for Time Variable Delay Reaction Diffusion Equations

报告摘要：A discontinuous Galerkin (DG) time stepping method is suggested for solving linear reaction diffusion differential equations (RDDEs) with time variable delay. We prove that, under a constrained mesh, the DG solution exhibits local superconvergence of order k ^(2q+1) at the mesh points. By constructing a projection operator, we further demonstrate that the DG solution exhibits k^(q+2) superconvergence rate at Radau II points. The theoretical findings of the developed scheme are validated through a series of numerical results.
