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.
