Abstract
We will introduce the general framework of adaptive finite element methods(FEMs) for elliptic equations, and discuss a posteriori error estimation and the algorithms. In particular, we present the adaptive FEMs for the Poisson equation with Dirac delta sources, talk about the difficulties of the problems, and demonstrate the results with a series of numerical simulations.
