报告题目 Multigrid Algorithm for the Coupling System of Natural Boundary Element Method and Finite Element Method for Unbounded Domain Problem

Abstract: In this talk, some V-cycle multigrid algorithms are presented for the coupling system arising from discretization the Dirichlet exterior problem by coupling the natural boundary element method and finite element method. The convergence of these multigrid algorithms is obtained even with only one smoothing on all levels and the rate of convergence is uniformly bounded independent of the number of levels and the mesh sizes of all levels which indicates that these multigrid algorithms are optimal.
