AbstractmFor the system of linear equations resulting from the discretization of the one-dimensional Poisson equation, we investigate the influences of the multiple splittings and the weighting matrices upon the convergence rate of the parallel matrix multisplitting method. The results show that the

Based on a new global variational formulation, a spectral element approximation of the incompressible Navier-Stokes/Euler coupled problem gives rise to a global discrete saddle problem. The classical Uzawa algorithm decouples the original saddle problem into two positive definite symmetric systems.
