We will discuss our on-going investigation of
hp-adaptive finite elements. We will focus on a posteriori
error estimates based on superconvergent derivative recovery.
Besides providing both global error estimates and local
error indicators, this family of error estimates also provides
information that forms the basis of our hp-adaptive refinement
and coarsening strategies. In particular, these a posteriori error
estimates address in a cost efficient and natural way the critical
issue of deciding between h or p refinement/coarsening. Some
numerical examples will be provided.
