Heterogeneous Domain Decomposition for Singularly Perturbed Elliptic Boundary Value Problems

A heterogeneous domain-decomposition method is presented for the numerical solution of singularly perturbed elliptic boundary value problems. The method, which is parallelizable at various levels, uses several ideas of asymptotic analysis. The subdomains match the domains of validity of the local (i...
