The Interface Probing Technique in Domain Decomposition
Copyright policy )The Interface Probing Technique in Domain Decomposition
The authors investigate an algebraic technique for constructing interface preconditioners in domain decomposition algorithms which can be used for solving linear systems arising from the discretization of elliptic partial differential equations. The method is based on the approximation of the interface matrices by matrices with a specified sparsity pattern. Many theoretical and numerical results are presented.
