Abstract : In the 1970’s Harary and Schwenk suggested the problem of classifying integral graphs. A graph is said to be integral if all eigenvalues of the adjacency matrix are integers. Since the general problem of classifying integral graphs seems too di?cult, special classes of graphs, including trees, graphs of bounded degree, regular graphs and Cayley graphs are investigated. In this talk we discuss recent progress on integral Cayley graphs.
