Regularity estimates of fractional heat semigroups related with uniformly elliptic operators

Honglei Shi, Pengtao Li, Kai Zhao

Let $L = - div (A (x) \cdot \nabla) + V (x)$ be a second-order uniformly elliptic operator on $R^{n}$ $(n \geq 3)$ , where $A (x)$ is a real symmetric matrix satisfying…

On Concentration Inequality of the Laplacian Matrix of Erdős-Rényi Graphs

Yiming Chen, Xuanang Hu, Pengtao Li

This paper focuses on the concentration properties of the spectral norm of the normalized Laplacian matrix for Erdős-Rényi random graphs. First, We achieve the optimal bound that c…

Sample complexity and weak limits of nonsmooth multimarginal Schrödinger system with application to optimal transport barycenter

Pengtao Li, Xiaohui Chen

Multimarginal optimal transport (MOT) has emerged as a useful framework for many applied problems. However, compared to the well-studied classical two-marginal optimal transport th…
