An hp-version discontinuous Galerkin method for integro-differential equations of parabolic type

, 2011
We study the numerical solution of a class of parabolic integro-differential equations with weakly singular kernels. We use an $hp$-version discontinuous Galerkin (DG) method for the discretization in time.
