"Domain decomposition methods enable parallel computation during the iterative solution of partial differential equations of elliptic tupe. In order to limit the number of iterations one must then use an efficient preconditioner which can significantlz reduce the condition number of the given problem and, at the same time, is highly parallelizable. In this paper we describe and analyzse such a preconditioner, which is based on local subdomain inverse matrices and is applicable for various types of domain decomposition methods."@en .
