We study in this thesis space-time domain decomposition methods, in particular, the Parareal method, the Optimized Schwarz Waveform Relaxation (OSWR) method and their coupling, applied to the numerical simulation of parabolic equations and of the Stokes equations. We first propose and analyze a coupling of the Parareal method with the OSWR method. The obtained coupled Parareal-OSWR method is a parallel method, both in the time and space directions, with only few OSWR iterations in the fine propagator in order to reduce computational costs and with a simple coarse propagator deduced from the Backward Euler method. The analysis of this coupled method is presented for a one-dimensional advection-reaction-diffusion equation. For the coupling of...
