The aim of this paper is to derive pointwise global and local best approximation type error estimates for biharmonic problems using theinterior penalty method. The analysis uses the technique of dyadic decompositions of the domain, which is assumed to be a convex polygon. The proofs require local energy estimates and new pointwise Green’s function estimates for the continuous problem which has independent interest. References
