这份报纸涉及缩放仪的微分方程打的延期的连续 Galerkin 解决方案的 superconvergent 点。我们在一致网孔下面证明本地人是连续 Galerkin 答案的节的 superconvergence 并且基于在连续 Galerkin 答案 U 和准确答案 u 的插值 hu 之间的 supercloseness 定位所有 superconvergent 点。理论结果被数字例子说明。 '

英文摘要：

This paper is concerned with the superconvergent points of the continuous Galerkin solutions for delay differential equations of pantograph type. We prove the local nodal superconvergence of continuous Galerkin solutions under uniform meshes and locate all the superconvergent points based on the supercloseness between the continuous Galerkin solution U and the interpolation Hhu of the exact solution u. The theoretical results are illustrated by numerical examples.
