We prove two-sided estimates of heat kernels on non-parabolic
Riemannian manifolds with ends, assuming that the heat kernel on each end separately
satisfies the Li-Yau estimate.

We study how bounds on the local geometry of a Riemannian
polyhedral complex yield uniform local Poincar′e inequalities. These
inequalities have a variety of applications, including bounds on the he...
