Characterizing the limiting critical Potts measures on locally regular-tree-like expander graphs

Hang Du, Yanxin Zhou

For any integers $d, q \geq 3$ , we consider the $q$ -state ferromagnetic Potts model with an external field on a sequence of expander graphs that converges to the $d$ -regular tree $\ma…

Sharp threshold for network recovery from voter model dynamics

Hang Du, Seokmin Ha, Oriol SolÃ©-Pi

We investigate the problem of recovering a latent directed ErdÅs-RÃ©nyi graph $G^{*} \sim G (n, p)$ from observations of discrete voter model trajectories on $G^{*}$ , where $n p$ …

For two unlabeled graphs $G_{1}, G_{2}$ independently sub-sampled from an ErdÅs-RÃ©nyi graph $G (n, p)$ by keeping each edge with probability $s$ , we aim to recover \emph{as many…
