Hypocoercivity meets lifts
Giovanni Brigati, Francis Lörler, Lihan Wang
We unify the variational hypocoercivity framework established by D. Albritton, S. Armstrong, J.-C. Mourrat, and M. Novack, with the notion of second-order lifts of reversible diffu…

Multivariate Gini-type discrepancies
Gennaro Auricchio, Giovanni Brigati, Paolo Giudici +1
Measuring distances in a multidimensional setting is a challenging problem, which appears in many fields of science and engineering. In this paper, to measure the distance between…

Explicit convergence rates of underdamped Langevin dynamics under weighted and weak Poincaré--Lions inequalities
Giovanni Brigati, Gabriel Stoltz, Andi Q. Wang +1
We study the long-time behavior of the underdamped Langevin dynamics, in the case of so-called \emph{weak confinement}. Indeed, any distribution (in position an…
