Sharp gradient estimate for heat kernels on $R C D^{*} (K, N)$ metric measure spaces

Jia-Cheng Huang, Hui-Chun Zhang

In this paper, we will establish an elliptic local Li-Yau gradient estimate for weak solutions of the heat equation on metric measure spaces with generalized Ricci curvature bounde…

A note on Liouville type theorem of elliptic inequality $Δ u + u^{σ} \leq 0$ on Riemannian manifolds

Hui-Chun Zhang

Let $σ > 1$ and let $M$ be a complete Riemannian manifold. In a recent work [9], Grigor $^{'}$ yan and Sun proved that a pointwise upper bound of volume growth is sufficient for u…

On a new definition of Ricci curvature on Alexandrov spaces

Hui-Chun Zhang, Xi-Ping Zhu

Recently, in [49], a new definition for lower Ricci curvature bounds on Alexandrov spaces was introduced by the authors. In this article, we extend our research to summarize the ge…
