Infinite collisions of simple random walks on random recursive trees generated by Bernoulli sequences

Jia-shan Tang, Feng Wang, Xian-Yuan Wu

In this paper, we study random recursive trees generated by Bernoulli sequences. Starting from a graph with two vertices and one edge, each new vertex is connected to the last vert…

An Explicit Description of Extreme Points of the Set of Couplings with Given Marginals: with Application to Minimum-Entropy Coupling Problems

Ya-Jing Ma, Feng Wang, Xian-Yuan Wu +1

Given probability distributions $p = (p_{1}, p_{2}, \dots, p_{m})$ and $q = (q_{1}, q_{2}, \dots, q_{n})$ with $m, n \geq 2$ , denote by $C (p, q)$ the set of all couplings of $\bf…
