Abstract Iterative substructuring Domain Decomposition (DD) methods have been
extensively studied, and they are usually associated with nonoverlapping decompositions. It …

We define a new two-level optimized Schwarz method (OSM), and we provide a
convergence analysis both for overlapping and nonoverlapping decompositions. The two …

The aim of this thesis is to contribute to the development of domain decomposition methods
which are techniques to solve efficiently large linear or nonlinear systems arising from the …
