We propose an improvement of the double sweep preconditioner for the solution of Helmholtz and Maxwell problems by an optimized Schwarz domain decomposition method.
The approximation of the posterior distribution associated to a Bayesian inverse problem is decomposed into a hierarchy consisting of a telescoping sum of increments with decreasing variance and incre
Singular polynomial eigenvalue problems arsie naturally in the vibration analysis of structures.Classical techniques,based on linearization may fail because linearizations do not preserve all the sing
