[HTML][HTML] Cosh gradient systems and tilting

MA Peletier, A Schlichting - Nonlinear Analysis, 2023 - Elsevier
We review a class of gradient systems with dissipation potentials of hyperbolic-cosine type.
We show how such dissipation potentials emerge in large deviations of jump processes …

[HTML][HTML] Graph-to-local limit for the nonlocal interaction equation

A Esposito, G Heinze, A Schlichting - Journal de Mathématiques Pures et …, 2025 - Elsevier
We study a class of nonlocal partial differential equations presenting a tensor-mobility, in
space, obtained asymptotically from nonlocal dynamics on localising infinite graphs. Our …

Scaling limits of the Wasserstein information matrix on Gaussian mixture models

W Li, J Zhao - arXiv preprint arXiv:2309.12997, 2023 - arxiv.org
We consider the Wasserstein metric on the Gaussian mixture models (GMMs), which is
defined as the pullback of the full Wasserstein metric on the space of smooth probability …

Evolutionary -Convergence of Entropic Gradient Flow Structures for Fokker--Planck Equations in Multiple Dimensions

D Forkert, J Maas, L Portinale - SIAM Journal on Mathematical Analysis, 2022 - SIAM
We consider finite-volume approximations of Fokker--Planck equations on bounded convex
domains in R^d and study the corresponding gradient flow structures. We reprove the …

Consistency and convergence for a family of finite volume discretizations of the Fokker–Planck operator

M Heida, M Kantner, A Stephan - ESAIM: Mathematical Modelling …, 2021 - esaim-m2an.org
We introduce a family of various finite volume discretization schemes for the Fokker–Planck
operator, which are characterized by different Stolarsky weight functions on the edges. This …

Homogenisation of dynamical optimal transport on periodic graphs

P Gladbach, E Kopfer, J Maas, L Portinale - Calculus of Variations and …, 2023 - Springer
This paper deals with the large-scale behaviour of dynamical optimal transport on Z d-
periodic graphs with general lower semicontinuous and convex energy densities. Our main …

On a class of nonlocal continuity equations on graphs

A Esposito, FS Patacchini… - European Journal of …, 2024 - cambridge.org
Motivated by applications in data science, we study partial differential equations on graphs.
By a classical fixed-point argument, we show existence and uniqueness of solutions to a …

EDP-convergence for a linear reaction-diffusion system with fast reversible reaction

A Stephan - Calculus of Variations and Partial Differential …, 2021 - Springer
We perform a fast-reaction limit for a linear reaction-diffusion system consisting of two
diffusion equations coupled by a linear reaction. We understand the linear reaction-diffusion …

On evolution PDEs on co-evolving graphs

A Esposito, L Mikolás - arXiv preprint arXiv:2310.10350, 2023 - arxiv.org
We provide a well-posedness theory for a class of nonlocal continuity equations on co-
evolving graphs. We describe the connection among vertices through an edge weight …

Gradient flow formulations of discrete and continuous evolutionary models: a unifying perspective

FACC Chalub, L Monsaingeon, AM Ribeiro… - Acta Applicandae …, 2021 - Springer
We consider three classical models of biological evolution:(i) the Moran process, an
example of a reducible Markov Chain;(ii) the Kimura Equation, a particular case of a …
