摘要

In this paper, the global superconvergences of the domaindecomposition methods with Lagrangian multiplier and nonmatching grids are proven for solving the second order elliptic boundary value problems. Moreover, L∞ and L2 error estimates are discussed and a defect correction scheme is presented.
