On the Stability of the Discontinuous Galerkin Method for the Heat Equation
This paper analyzes stability properties of a class of discontinuous Galerkin methods for the heat equation. It is shown that the finite element projection associated with these methods is stable with respect to a mesh-dependent norm--a discrete analogue of the space-time L2-norm. Optimal order-regu...

It is shown that the finite element projection associated with these methods is stable with respect to a mesh-dependent norm--a discrete analogue of the space-time L2-norm. Optimal order-regularity error bounds in L2([ 0, T ]; L2(Ω)) are derived. |
