hus preconditioned system matrix depends on the subdomain diameter (∼ 1/..), the width of the over lap (∼1/δ) and the diffusion coefficient jump (∼max./min.). If the additive Schwarz preconditioner is equipped with a coarse subspace, the condition number estimate is reduced to .[.] and in the case o
