Abstract: A graph is called integral if its eigenvalues are integers. We provide necessary and sufficient conditions for a Cayley graph over a finite symmetric algebra R to be integral. This generalizes the work of So who studies the case where R is the ring of integers modulo n. (Joint work with Tung T. Nguyen).
