Oriented or signed Cayley graphs with all eigenvalues integer multiples of $Δ$

Chris Godsil, Xiaohong Zhang

Let $G$ be a finite abelian group. Bridges and Mena characterized the Cayley graphs of $G$ that have only integer eigenvalues. Here we consider the $(0, 1, - 1)$ adjacency matrix of a…

Block-transitive and point-primitive $2$ - $(v, k, 2)$ designs with sporadic socle

Xiaohong Zhang, Shenglin Zhou

The purpose of this paper is to classify all pairs $(D, G)$ , where $D$ is a non-trivial $2$ - $(v, k, 2)$ design, and $G \leq A u t (D)$ acts transitively o…
