The Feller property on Riemannian manifolds

Stefano Pigola, Alberto G. Setti

The asymptotic behavior of the heat kernel of a Riemannian manifold gives rise to the classical concepts of parabolicity, stochastic completeness (or conservative property) and Fel…

The connectivity at infinity of a manifold and $L^{q, p}$ -Sobolev inequalities

Stefano Pigola, Alberto G. Setti, Marc Troyanov

The purpose of this paper is to give a self-contained proof that a complete manifold with more than one end never supports an $L^{q, p}$ -Sobolev inequality ( $2 \leq p$ , $q\leq p^{*}…

Ricci almost solitons

Stefano Pigola, Marco Rigoli, Michele Rimoldi +1

We introduce a natural extension of the concept of gradient Ricci soliton: the Ricci almost soliton. We provide existence and rigidity results, we deduce a-priori curvature estimat…
