Rapid mixing of the flip chain over non-crossing spanning trees

Konrad Anand, Weiming Feng, Graham Freifeld +3

We show that the flip chain for non-crossing spanning trees of $n + 1$ points in convex position mixes in time $O (n^{8} lo g n)$ . We use connections between Fuss-Catalan structures to c…

Optimal Mixing Time for the Ising Model in the Uniqueness Regime

Xiaoyu Chen, Weiming Feng, Yitong Yin +1

We prove an optimal $O (n lo g n)$ mixing time of the Glauber dynamics for the Ising models with edge activity $β \in (\frac{Δ - 2}{Δ}, \frac{Δ}{Δ - 2})$ . This mixing time bound h…
