Global heat kernel estimates
This paper is concerned with gradient estimates and Harnack inequalities for positive solutions on compact Riemannian manifolds \(M\) with boundary. The author defines the ``interior rolling \(R\)-ball'' condition and generalizes results of P. Li and S. T. Yau to the case in which \(M\) has a (possibly nonconvex) boundary satisfying this condition.
