Wasserstein Stability, Couplings Across Volumes, and the $1 + 1/ d$ Moment Thresholds in the Edwards--Anderson Model

Mauris Chueng, Hexiang Wang, Keheng Zhu

We study the quenched pressure of the nearest-neighbor Edwards--Anderson Ising model with free and periodic boundary conditions. First, we prove that the infinite-volume pressure i…

The exponent of harmonic LCM avoidance

Yanping Luo, Ruiyi Yang, Keheng Zhu

Fix $k \geq 3$ , and let $f_{k} (N)$ be the largest harmonic sum of a subset of $[N]$ containing no $k$ distinct integers with a common pairwise least common multiple. We prove that $f_k…
