Adaptive finite element methods for elliptic equations with non-smooth coefficients
This paper concerns a second-order elliptic equation with discontinuous or anisotropic coefficients in a bounded two- or three-dimensional polyhedral domain with a Lipschitz-continuous boundary, and its finite element discretization. Some a priori and a posteriori error estimates in an appropriate norm, which are independent of the variation of the coefficients, are proved.
