第三十七讲——宾州州立大学洪庆国博士学术报告


题目:Extended Galerkin Framework

时间:2023年6月6日(周二)下午16:00——17:00

地点:理学实验楼314室

报告人:洪庆国博士

摘要:In this talk, I will present an extended Galerkin framework for the design and analysis of conforming, nonconforming and discontinuous Galerkin methods for partial differential equations. By introducing appropriate multiple discretization variables, most existing and new Galerkin methods can be derived in a unified framework and the well-posedness and error estimates for these methods can be estimated within the same framework by using the standard Brezzi theory for mixed method. Examples will be given for Laplacian and elasticity equations.
