On the boundary Carrollian conformal algebra

Lucas Buzaglo, Xiao He, Tuan Anh Pham +3

The paper develops the mathematical theory of the boundary Carrollian conformal algebra (BCCA), constructing various modules, establishing irreducibility criteria, and introducing…

Bounded cohomology, quotient extensions, and hierarchical hyperbolicity

Francesco Fournier-Facio, Giorgio Mangioni, Alessandro Sisto

The authors introduce bounded central extensions (those whose Euler class is represented by a bounded cocycle) and prove that such extensions of hierarchically hyperbolic groups (H…

A Distributed Plug-and-Play MCMC Algorithm for High-Dimensional Inverse Problems

Maxime Bouton, Pierre-Antoine Thouvenin, Audrey Repetti +1

Markov Chain Monte Carlo (MCMC) algorithms are standard approaches to solve imaging inverse problems and quantify estimation uncertainties, a key requirement in absence of ground-t…

Intersection cohomology of Popov-Vinberg varieties

Andrew Dancer, Johan Martens, Nicholas Proudfoot

The Popov-Vinberg variety of a simply connected, split, semisimple algebraic group is a singular affine variety that contains the basic affine space as a Zariski open sub…

Spectral asymmetry via pseudodifferential projections: the massless Dirac operator

Matteo Capoferri, Beatrice Costeri, Claudio Dappiaggi

A new approach to the study of spectral asymmetry for systems of partial differential equations (PDEs) on closed manifolds was proposed in a recent series of papers by the first au…

Semi-discrete optimal transport techniques for the compressible semi-geostrophic equations

David P. Bourne, Charlie P. Egan, Théo Lavier +1

We prove existence of weak solutions of the 3D compressible semi-geostrophic (SG) equations with compactly supported measure-valued initial data. These equations model large-scale…
