Abstract: Spectral problems for the Dirac operator with regular but not strongly regular boundary conditions and complex‐valued potential summable over a finite interval are considered. The purpose of this paper is to find conditions under which… read more here.

Abstract: We consider and analyze applying a spectral inverse iteration algorithm and its subspace iteration variant for computing eigenpairs of an elliptic operator with random coefficients. With these iterative algorithms the solution is sought from a… read more here.
