Florentin Münch (MPI MIS, Leipzig): Ollivier curvature and continuous time
Dez 18 @ 15:00 – 16:00

We provide a generalization of Ollivier curvature to weighted graphs with potentially unbounded Laplacian. An immediate consequence of this is a discrete version of the Laplacian comparison principle. We give a continuous time heat semigroup characterization of lower bounds on the Ollivier curvature via the perpetual cutoff method. Using this, we show that a lower bound on the Ollivier curvature implies stochastic completeness.

Ben Seeger (University of Chicago): Scaling limits and homogenization for mixing Hamilton-Jacobi equations
Dez 18 @ 15:15 – 16:15

Vortrag in der Reihe: Arbeitsgemeinschaft ANGEWANDTE ANALYSIS
I will present results about scaling limits of Hamilton-Jacobi
equations with highly oscillatory, mixing spatio-temporal dependence. When
the Hamiltonian is centered, then the long time, large space behavior of
the solutions is governed by a spatially homogenous, stochastic
Hamilton-Jacobi equation. The result relies on explicit convergence rates
for the stochastic homogenization of Hamilton-Jacobi equations and new
stability estimates for stochastic viscosity solutions. I will also
discuss a class of problems for which the hyperbolic scaling limit leads
to spatio-temporal stochastic homogenization.

Dez 19 @ 11:00 – 12:00

This talk aims to answer the following question: What do we know about the variety defined by the k-signature of an axis path? This is part of the work done during my visit to the MPI together with Mateusz Michalek and Francesco Galuppi.
