Title: An optimal adaptive Fictitious Domain Method
Abstract:
We consider a Fictitious Domain formulation of an elliptic PDE, and solve the arising saddle-point problem by an inexact preconditioned Uzawa iteration.
Solving the arising `inner' elliptic problems with an adaptive finite element method, we prove that the overall method converges with the best possible rate.
This is joint work with S. Berrone (Torino), A. Bonito (Texas A&M), and M. Verani (Milano).
