Sharp estimates and inequalities on Riemannian manifolds with Euclidean volume growth
Luigi Fontana, Carlo Morpurgo, Liuyu Qin
We obtain sharp estimates for heat kernels and Green's functions on complete noncompact Riemannian manifolds with Euclidean volume growth and nonnegative Ricci curvature. We will t…

Moser-Trudinger inequalities: from local to global
Luigi Fontana, Carlo Morpurgo, Liuyu Qin
Given a general complete Riemannian manifold , we introduce the concept of "local Moser-Trudinger inequality on ". We show how the validity of the Moser-Trudinger in…
