Stability estimates for h-p spectral element methods for elliptic problems
The authors consider Poisson's equation in a plane polygon with Dirichlet boundary conditions. They suggest that the difficulties associated with the corners may be overcome by using Kondratiev's modified polar coordinates centred on the corners. Stability estimates are discussed and error estimates obtained. There is not however any indication of any actual application of the theory.
