Finite element approximations in a nonlipschitz domain

In this paper we analyze the approximation by standard piecewise linear finite elements of a nonhomogeneous Neumann problem in a cuspidal domain. Since the domain is not Lipschitz, many of the results on Sobolev spaces, which are fundamental in the usual error analysis, do not apply. Therefore, we n...
