Approximation in Metric Sobolev Spaces: A General Framework

Massimo Fornasier, Giacomo Enrico Sodini

In our recent work [FHS25], we introduced a numerical framework for approximating Sobolev functions on Wasserstein spaces from finite samples, leveraging structural properties esta…

The Brezis-Ekeland-Nayroles principle in metric spaces: time-continuous setting

Pierre-Cyril Aubin-Frankowski, Giacomo Enrico Sodini, Ulisse Stefanelli

Based on a variational characterization of the local slope of a functional, we extend the celebrated Brezis-Ekeland-Nayroles null-minimization principle to curves of maximal slope…

Functions of bounded variation and Lipschitz algebras in metric measure spaces

Enrico Pasqualetto, Giacomo Enrico Sodini

Given a unital algebra of locally Lipschitz functions defined over a metric measure space , we study two associated notions of f…

A Lagrangian approach to totally dissipative evolutions in Wasserstein spaces

Giulia Cavagnari, Giuseppe Savaré, Giacomo Enrico Sodini

We introduce and study the class of totally dissipative multivalued probability vector fields (MPVF) on the Wasserstein space $(\mathcal{P}_2(\mathsf{X}),W…

Evolution variational inequalities with general costs

Pierre-Cyril Aubin-Frankowski, Giacomo Enrico Sodini, Ulisse Stefanelli

We extend the theory of gradient flows beyond metric spaces by studying evolution variational inequalities (EVIs) driven by general cost functions , including Bregman and entrop…

HJB equations driven by the Dirichlet-Ferguson Laplacian in Wasserstein-Sobolev spaces

François Delarue, Mattia Martini, Giacomo Enrico Sodini

We study linear and nonlinear PDEs defined on the space of over the flat torus , equipped with the Dirichlet-Ferguson measure $\mathcal{D}…
