摘要：
We propose and analyze a new hybrid finite elements domain decomposition method for solving an elliptic problem. In this method we can use different finite element approximations in each subdomains; the matching conditions on the interfaces are obtained with two Lagrange multipliers and a mortar element. Optimal results are obtained for a model second-order problem.
