Convergence results with natural norms: Stabilized Lagrange multiplier method for elliptic interface problems
Sanjib Kumar Acharya, Ajit Patel
A stabilized Lagrange multiplier method for second order elliptic interface problems is presented in the framework of mortar method. The requirement of LBB (Ladyzhenskaya-Babuška-B…
