Overlapping Schwarz methods with GenEO coarse spaces for indefinite and nonself-adjoint problems

Abstract Generalized eigenvalue problems on the overlap(GenEO) is a method for computing an operator-dependent spectral coarse space to be combined with local solves on subdomains to form a robust parallel domain decomposition preconditioner for elliptic PDEs. It has previously been proved, in the s...
