Thema: | hp Discontinuous Galerkin Time-stepping for parabolic problems |
We present an hp-Error analysis for the discontinuous Galerkin
time-stepping scheme for abstract parabolic equations. We show
for semidiscretization in time (Rothe's method)
under realistic assumptions
(polygonal or polyhedral domain, incompatible initial data,
indefinite, nonselfadjoint spatial operators) that
We describe a parallel implementation based on modal decoupling in time which reduces the CPU for one time step with any order r>=0 to that required by backward Euler. Numerical examples confirm the theory. This is joint work with D. Schoetzau (Minnesota/Basel).
