Angefertigt mit der Genehmigung der Mathematisch-Summary This thesis consists of four parts all of which deal with different aspects of Hodge classes on self-products of K3 surfaces. In the first three parts we present three different strategies to tackle the Hodge conjecture for self-products of K3 surfaces. The first approach is of deformation theoretic(More)

In this paper we show the regularity of the strain tensor and local differentiability of the stress tensor and hardening parameters in plasticity with hardening using a viscoplastic type penalisation in the case of von Mises yield criterion. The regularity of the strain tensor was first shown by Johnson [Joh78] by constructing a bijection between the(More)
