The solution of large linear problems is one of the most time consuming kernels in many numerical simulations. On the one hand, the computational linear algebra community has developed several high performance linear solvers that only require algebraic information (the matrix K and its associated right-hand side f) to compute the solution x such that Ku = f. On the other hand, the Domain Decomposition (DD) community has developed many efficient and robust methods in the last decades, that take into account the underlying partial differential equation and the geometry to accelerate the solution of such problems. In this thesis, both approaches are combined: an analysis of coarse correction for abstract Schwarz (aS) DD solvers is proposed, le...
