A generalization of quantum pair state transfer

Sooyeong Kim, Hermie Monterde, Bahman Ahmadi +3

An $s$ -pair state in a graph is a quantum state of the form $e_{u} + s e_{v}$ , where $u$ and $v$ are vertices in the graph and $s$ is a non-zero complex number. If $s=-1…

Bounds on Kemeny's constant of a graph and the Nordhaus-Gaddum problem

Sooyeong Kim, Neal Madras, Ada Chan +3

We study Nordhaus-Gaddum problems for Kemeny's constant $K (G)$ of a connected graph $G$ . We prove bounds on $min {K (G), K (G)}$ and the pro…
