Discretization of Semicoercive Variational Inequalities
In this contribution we report on recent progress towards approximation and discretization theory for semicoercive variational inequalities. We discuss a broad range of applications: approximation and stability results for finite dimensional semidefinite quadratic optimization problems, convergence results for finite element discretizations and for boundary element discretizations of steady-state unilateral problems in mathematical physics, approximation results for elliptic control problems.
