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

Hang Du, Yanxin Zhou

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

Sharp threshold for network recovery from voter model dynamics

Hang Du, Seokmin Ha, Oriol Solé-Pi

We investigate the problem of recovering a latent directed Erdős-Rényi graph from observations of discrete voter model trajectories on , where …

Optimal recovery of correlated Erdős-Rényi graphs

Hang Du

For two unlabeled graphs independently sub-sampled from an Erdős-Rényi graph by keeping each edge with probability , we aim to recover \emph{as many…
