Completely Transitive Designs

Chris D. Godsil, Cheryl E. Praeger

We view a design $D$ as a set of $k$ -subsets of a fixed set $X$ of $v$ points. A $k$ -subset of $X$ is at distance $i$ from $D$ if it intersects some $k$ -set in…

Rationality conditions for the eigenvalues of normal finite Cayley graphs

Chris Godsil, Pablo Spiga

Given a finite group G, we say that a subset C of G is power-closed if, for every x in C and y in <x> with <x>=<y>, we have that y lies in C. In this paper we are interested in fin…

Perfect state transfer on distance-regular graphs and association schemes

Gabriel Coutinho, Chris Godsil, Krystal Guo +1

We consider the representation of a continuous-time quantum walk in a graph $X$ by the matrix $exp (i t A (X))$ . We provide necessary and sufficient criteria for distance-regular grap…
