We propose a Schwarz-based domain decomposition method for solving a dis- persion equation consisting on the linearized KdV equation without the ad- vective term, using simple

There are five main techniques to prove the convergence of Domain Decomposition Algorithms and they are: Orthorgonal Projection used for a linear Laplace equation (see [16]), Fourier

When using overlapping subdomains and “classical” Schwarz waveform relaxation -by a Dirichlet exchange of informations on the boundary- the so defined algorithm converges in a

This algorithm is like a classical overlapping additive Schwarz, but on subdomains, a time dependent problem is solved, like in waveform relaxation.. Thus the name overlapping
