| Abstract: | This paper is concerned with the application of the discontinuous Galerkin method for delay differential equations (DDEs) with nonlinear delay. Based on quasi-graded meshes, we get the global convergence and local superconvergence of discontinuous Galerkin solutions for DDEs. Theoretical results are illustrated by numerical examples. |
