New formulas for the Laplacian of distance functions and applications
F Cavalletti, A Mondino - Analysis & PDE, 2020 - msp.org
The goal of the paper is to prove an exact representation formula for the Laplacian of the
distance (and more generally for an arbitrary 1-Lipschitz function) in the framework of metric …

The Ricci flow under almost non-negative curvature conditions
RH Bamler, E Cabezas-Rivas, B Wilking - Inventiones mathematicae, 2019 - Springer
We generalize most of the known Ricci flow invariant non-negative curvature conditions to
less restrictive negative bounds that remain sufficiently controlled for a short time. As an …

The geodesic X-ray transform with matrix weights
Consider a compact Riemannian manifold of dimension $\geq 3$ with strictly convex
boundary, such that the manifold admits a strictly convex function. We show that the …

[HTML][HTML] Ricci flow under local almost non-negative curvature conditions
Y Lai - Advances in Mathematics, 2019 - Elsevier
We find a local solution to the Ricci flow equation under a negative lower bound for many
known curvature conditions. Under a non-collapsing assumption, the flow exists for a …

Duality between Ahlfors-Liouville and Khas' minskii properties for nonlinear equations
L Mari, LF Pessoa - arXiv preprint arXiv:1603.09113, 2016 - arxiv.org
In recent years, the study of the interplay between (fully) non-linear potential theory and
geometry received important new impulse. The purpose of this work is to move a step further …
