Consistent and convergent discretizations of Helfrich-type energies on general meshes

Vincent Degrooff, Peter Gladbach, Heiner Olbermann

We show that integral curvature energies on surfaces of the type $E_{0} (M) := \int_{M} f (x, n_{M} (x), D n_{M} (x)) d H^{2} (x)$ have discrete versions for triangular complexes, where t…

Stochastic homogenisation of nonlinear minimum-cost flow problems

Peter Gladbach, Jan Maas, Lorenzo Portinale

This paper deals with the large-scale behaviour of nonlinear minimum-cost flow problems on random graphs. In such problems, a random nonlinear cost functional is minimised among al…
