Phd thesis (2014)

Robust Domain Decomposition Methods for Symmetric Positive Definite Problems (manuscript).

I was a PhD student at Laboratoire Jacques Louis Lions in Paris between September 2010 and January 2014. My advisors were Frédéric Nataf (LJLL) and Patrice Hauret (Michelin).

Code

Loïc Gouarin and I have written a domain decomposition code in PETSc4py. It incorporates the GenEO coarse spaces (for Additive Schwarz and Neumann-Neumann) as well as adaptive multipreconditioned CG.
