Resumen:
We present a posteriori error estimates for second order elliptic problems with point sources in two- and three-dimensional domains. We state a global upper bound and a local lower bound for the error measured in a weighted Sobolev space. The weight considered is a power of the distance to the support of the Dirac delta source term. Numerical experiments with an adaptive algorithm yield optimal meshes and very good effectivity indices.
