Failure of curvature-dimension conditions on sub-Riemannian manifolds via tangent isometries

Luca Rizzi, Giorgio Stefani

We prove that, on any sub-Riemannian manifold endowed with a positive smooth measure, the Bakry-Émery inequality for the corresponding sub-Laplacian implies the existence of enough…

Unified synthetic Ricci curvature lower bounds for Riemannian and sub-Riemannian structures

Davide Barilari, Andrea Mondino, Luca Rizzi

Recent advances in the theory of metric measures spaces on the one hand, and of sub-Riemannian ones on the other hand, suggest the possibility of a "great unification" of Riemannia…

Global Kodaira Spencer class and Massey products

Luca Rizzi, Francesco Zucconi

We define a new notion of supported global deformation class for a semistable family of complex varieties over a curve . We use this notion to study when , possi…

Cosmicflows-4

R. Brent Tully, Ehsan Kourkchi, Hélène M. Courtois +14

With Cosmicflows-4, distances are compiled for 55,877 galaxies gathered into 38,065 groups. Eight methodologies are employed, with the largest numbers coming from the correlations…

Local Systems, Algebraic Foliations and Fibrations

Luca Rizzi, Francesco Zucconi

Given a semistable fibration we introduce a correspondence between foliations on and local systems on . Building up on this corre…
