Abstract. We discuss the notion of irreducible block Schur decomposition of a complex square matrix and show how such a decomposition provides information about singularities in th...
In this article we present the first results on domain decomposition methods for nonlocal operators. We present a nonlocal variational formulation for these operators and establi...
Application of the hierarchical Schur algorithm to the boundary element method for 3D capacitance extraction shifts the speed bottleneck from inversion of the influence matrix to...
