Relaxed Kacanov scheme for the p-Laplacian with large p
Anna Kh. Balci, Lars Diening, Johannes Storn
We introduce a globally convergent relaxed Kacanov scheme for the computation of the discrete minimizer to the -Laplace problem with . The iterative scheme is…

A Space-Time DPG Method for the Heat Equation
Lars Diening, Johannes Storn
This paper introduces an ultra-weak space-time DPG method for the heat equation. We prove well-posedness of the variational formulation with broken test functions and verify quasi-…

The parabolic p-Laplacian with fractional differentiability
Dominic Breit, Lars Diening, Johannes Storn +1
We study the parabolic -Laplacian system in a bounded domain. We deduce optimal convergence rates for the space-time discretization based on an implicit Euler scheme in time. Ou…
