Analysis and Preconditioning of a Probabilistic Domain Decomposition Algorithm for Elliptic Boundary Value Problems

We perform a rigorous numerical analysis of the PDDSparse algorithm [Bernal, Morón-Vidal & Acebrón, Comp.Math.& App. 146 (2023)] for domain decomposition of partial differential equations. PDDSparse is a novel, recently introduced parallelisation paradigm for solving large-scale elliptic bou...
