The macro{hybrid formulation based on domain decomposition is considered for elliptic boundary value problems with both symmetric positive deenite and indeenite operators. The problem is discretized by the mortar element method, which leads to a large{scale sparse linear system with a saddle{ point matrix. In the case of symmetric and positive deenite operators, a block diagonal preconditioner ...

A finite element method, called generalized Weak Galerkin (gWG), is introduced for the Stokes equation by using a new weak gradient notion in usual approach. The gWG method allows polynomial elements of arbitrary order any combination velocity variable, but with proper constraints on pressure due to inf-sup condition. Error estimates are derived approximation mesh-dependent energy norm, as well...

Abstract We present a convergence theory for Optimized Schwarz Methods that rely on nonlocal exchange operator and covers the case of coercive possibly nonselfadjoint impedance operators. This analysis also naturally deals with presence cross-points in subdomain partitions arbitrary shape. In particular hermitian positive definite impedance, we recover proposed Claeys & Parolin (2021).
