Time Discretization Schemes for Hyperbolic Systems on Networks by ε-Expansion

[OWP-2019-03] Altmann, Robert; Zimmer, Christoph (Mathematisches Forschungsinstitut Oberwolfach, 2019-02-12)

We consider partial differential equations on networks with a small parameter $\epsilon$ , which are hyperbolic for $\epsilon>0$ and parabolic for $\epsilon=0$ . With a combination of an $\epsilon$ -expansion and Runge-Kutta ...
Weighted Surface Algebras: General Version

[OWP-2019-07] Erdmann, Karin; Skowroński, Andrzej (Mathematisches Forschungsinstitut Oberwolfach, 2019-02-28)

We introduce general weighted surface algebras of triangulated surfaces with arbitrarily oriented triangles and describe their basic properties. In particular, we prove that all these algebras, except the singular disc, ...
