WebWell-posedness is rigorously established in the paper for the Picard linearization of the fully nonlinear systems by using the Brezzi theory, which naturally leads to robust (and optimal) preconditioners for the linearized systems. WebThen, we apply the Babuŝka-Brezzi theory to prove the well-posedness of the corresponding continuous and discrete formulations. In particular, we show that Raviart …
