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 …

[HTML][HTML] A variational approach to the mean field planning problem

C Orrieri, A Porretta, G Savaré - Journal of Functional Analysis, 2019 - Elsevier
We investigate a first-order mean field planning problem of the form {−∂ t u+ H (x, D u)= f (x,
m) in (0, T)× R d,∂ tm−∇⋅(m H p (x, D u))= 0 in (0, T)× R d, m (0,⋅)= m 0, m (T,⋅)= m T in R …

A mean-field games laboratory for generative modeling

BJ Zhang, MA Katsoulakis - arXiv preprint arXiv:2304.13534, 2023 - arxiv.org
We demonstrate the versatility of mean-field games (MFGs) as a mathematical framework for
explaining, enhancing, and designing generative models. In generative flows, a Lagrangian …

Doubly nonlinear equations as convex minimization

G Akagi, U Stefanelli - SIAM Journal on Mathematical Analysis, 2014 - SIAM
We present a variational reformulation of a class of doubly nonlinear parabolic equations as
(limits of) constrained convex minimization problems. In particular, an ε-dependent family of …

Convergence of some mean field games systems to aggregation and flocking models

M Bardi, P Cardaliaguet - Nonlinear Analysis, 2021 - Elsevier
For two classes of Mean Field Game systems we study the convergence of solutions as the
interest rate in the cost functional becomes very large, modelling agents caring only about a …

On the p-Laplacian evolution equation in metric measure spaces

W Górny, JM Mazón - Journal of Functional Analysis, 2022 - Elsevier
The p-Laplacian evolution equation in metric measure spaces has been studied as the
gradient flow in L 2 of the p-Cheeger energy (for 1< p<∞). In this paper, using the first-order …

Integral convexity and parabolic systems

V Bögelein, B Dacorogna, F Duzaar, P Marcellini… - SIAM Journal on …, 2020 - SIAM
In this work we give optimal, ie, necessary and sufficient, conditions for integrals of the
calculus of variations to guarantee the existence of solutions---both weak and variational …

A new minimum principle for Lagrangian mechanics

M Liero, U Stefanelli - Journal of nonlinear science, 2013 - Springer
We present a novel variational view at Lagrangian mechanics based on the minimization of
weighted inertia-energy functionals on trajectories. In particular, we introduce a family of …

Geometry and analytic properties of the sliced Wasserstein space

S Park, D Slepčev - arXiv preprint arXiv:2311.05134, 2023 - arxiv.org
The sliced Wasserstein metric compares probability measures on $\mathbb {R}^ d $ by
taking averages of the Wasserstein distances between projections of the measures to lines …

On the existence and Hölder regularity of solutions to some nonlinear Cauchy–Neumann problems

A Audrito - Journal of Evolution Equations, 2023 - Springer
We prove uniform parabolic Hölder estimates of De Giorgi–Nash–Moser type for sequences
of minimizers of the functionals E ε (W)=∫ 0∞ et/ε ε {∫ R+ N+ 1 ya ε|∂ t W| 2+|∇ W| 2 d …
