Augmenting the Delsarte bound: a forbidden interval for the order of maximal cliques in strongly regular graphs
In this paper, we study the order of a maximal clique in an amply regular graph with a fixed smallest eigenvalue by considering a vertex that is adjacent to some (but not all) vertices of the maximal clique. As a consequence, we show that if a strongly regular graph contains a Delsarte clique, then...
