A posteriori error estimates for elliptic problems with Dirac measure terms in weighted spaces
Agnelli, Juan Pablo; Garau, Eduardo Mario; Morin, Pedro (2014)In this article we develop a posteriori error estimates for second order linear elliptic problems with point sources in two- and three-dimensional domains. We prove a global upper bound and a local lower bound for the error ...
