Abstract
There are two main difficulties in solving higher order elliptic boundary value problems: the discretization schemes are more complicated and the discrete problems are very ill-conditioned.  In this talk we will discuss an approach that can solve higher order problems with an efficiency similar to that for second order problems. It is based on discontinuous Galerkin methods, embedded multigrid algorithms and domain decomposition techniques.
