求解奇异摄动Volterra积分微分方程的 LDG-CFEM耦合方法

摘要

介绍了求解奇异摄动Volterra积分微分方程的LDG-CFEM耦合方法。数值算例表明，在局部加密Shishkin网格下， LDG-CFEM方法不仅稳定，而且精度高。%This paper introduces the coupled(LDG-CFEM) method for solving singularly perturbed Volterra integro- differential equations. Numerical results demonstrate that LDG-CFEM method not only is stable, but also has high accuracy under the Shishkin mesh.
