| Abstract: | In this paper the numerical solution of obstacle variational inequality problems associated with second order elliptic operators is considered.A class of nonoverlapping domain decomposition method with Lagrangian multipliers and nonmatching grids is proposed.Convergence theorem and convergence rate of the method are established. |
| Keywords: | obstacle problem non-overlapping domain decomposition Lagrangian multiplier nonmatching grid |
