Resumen
Artículo de publicación ISI The aim of this paper is to introduce residual type a posteriori error
estimators for a Poisson problem with a Dirac delta source term, in Lp norm
and W1,p seminorm. The estimators are proved to yield global upper and local
lower bounds for the corresponding norms of the error. They are used to guide
adaptive procedures, which are experimentally shown to lead to optimal orders
of convergence.
