应兰州大学数学与统计学院邓伟华教授的邀请,北京大学李若教授将于2018年9月28日至9月30日访问兰州大学,期间将举办专题学术报告。

报告题目:Can DG go beyond FE in efficiency ?

时 间:9月30日上午 09:00

地 点:齐云楼815

报告摘要:The discontinuous Galerkin method has attracted tremendous amount of attentions in the last decades since it has been applied to problems with regular solutions, the 2nd order elliptic equation for example. In spite of its well-known advantages, the efficiency of discontinuous Galerkin method for problems with very regular solutions is a weak point which has often been attacked at. In this talk, I will show that the discontinuous Galerkin method may go beyond the continuous finite element method in efficiency for elliptic problems, where is the traditional area for the finite element method to outperform. Our technique to help DG out is to construct a brand-new approximate space which will be clarified in my talk.

欢迎广大师生光临!
