years, accompanied by spectacular breakthroughs and deep new insights. In this survey, I …

Jump processes as generalized gradient flows

MA Peletier, R Rossi, G Savaré, O Tse - Calculus of Variations and Partial …, 2022 - Springer
We have created a functional framework for a class of non-metric gradient systems. The
state space is a space of nonnegative measures, and the class of systems includes the …

Consider the Monge-Kantorovich problem of transporting densities $\rho_0 $ to $\rho_1 $
on $\mathbb {R}^ d $ with a strictly convex cost function. A popular relaxation of the problem …

Entropy dissipation of Fokker-Planck equations on graphs

SN Chow, W Li, H Zhou - arXiv preprint arXiv:1701.04841, 2017 - arxiv.org
We study the nonlinear Fokker-Planck equation on graphs, which is the gradient flow in the
space of probability measures supported on the nodes with respect to the discrete …

Nonlocal-interaction equation on graphs: gradient flow structure and continuum limit

A Esposito, FS Patacchini, A Schlichting… - Archive for Rational …, 2021 - Springer
We consider dynamics driven by interaction energies on graphs. We introduce graph
analogues of the continuum nonlocal-interaction equation and interpret them as gradient …
