摘要: In this talk, we shall answer a long-standing open problem: Is it true that the convergence rate of the Lion's Robin-type nonoverlapping domain decomposition method can be optimal, independent of the mesh size? Furthermore, we shall consider the convergence behavior of the Robin-type domain decomposition for the Helmholtz equation.
