 We solve a long-standing open problem: Is it true that the convergence rate of the Lions'  Robin-Robin  nonoverlapping domain  decomposition (DD) method can be constant,independent of the mesh size h?  We closed this twenty-year old problem with a positive answer. Numerical results are presented verifying our analysis.
