In this paper, a relaxed Hermitian and skew-Hermitian splitting (RHSS) preconditioner is proposed for saddle point problems from the element-free Galerkin (EFG) discretization method. The EFG method is one of the...

Furthermore, error estimates for the approximate solutions of Signorini problems are given. In addition, we show that the Signorini problem may be ... Hou,De,Han - 《Mathematics of Computation》 被引量: 0发表: 1990年 Algebraic multigrid (AMG) for saddle point systems from meshfree discretizatio...
Meshfree methods are suitable for solving problems on irregular domains, avoiding the use of a mesh. To deal with the boundary conditions, we can use Lagrange Multiplier and obtain a sparse, symmetric and indenit...
