Heat kernel for reflected diffusion and extension property on uniform domains
Probability theory and related fields, 2023We study reflected diffusion on uniform domains where the underlying space admits a symmetric diffusion that satisfies sub-Gaussian heat kernel estimates.

Heat kernel on Ricci shrinkers
Calculus of Variations and Partial Differential Equations, 2019In this paper, we systematically study the heat kernel of the Ricci flows induced by Ricci shrinkers. We develop several estimates which are much sharper than their counterparts in general closed Ricci flows. Many classical results, including the optimal

Understanding the adaptive changes in maize kernel under high temperature stress (HTS) during grain formation, is critical for developing strategies to alleviate the negative effects of HTS on grain yield and quality.

Studying the heat semigroup, we prove Li–Yau-type estimates for bounded and positive solutions of the heat equation on graphs. These are proved under the assumption of the curvature-dimension inequality CDE ′ ( n , 0 ) {\mathrm{CDE}^{\prime}(n,0 ...

We prove a sharper pointwise upper bound for the heat kernel of the continuous time random walk on a general graph under a weaker assumption than that by \textit{I. Chavel} and \textit{E. A. Feldman} in `Modified isoperimetric constants and large time heat diffusion in Riemannian manifolds', preprint 1990. Our main result is stated in Theorem 2.6.

This is the main chapter of the book describing the crucial ingredients of the heat kernel method. It is an enhanced version of the singular perturbation method described in the previous chapter due to a heavy use of geometric techniques. The main goal is to compute the short-time asymptotic expansion of the heat kernel and the corresponding expansion ...
