Addressing the Petersen graph

Motivated by a problem on message routing in communication networks, Graham and Pollak proposed a scheme for addressing the vertices of a graph G by N -tuples of three symbols in such a way that distances between vertices may readily be determined from their addresses. They observed that N ≥ h(D), the maximum of the number of positive and the number of negative eigenvalues of the distance matri...

Optimal Generalized Petersen Graphs

In this paper we establish a theorem on the maximum number of vertices of a generalized Petersen graph as a function of the diameter.
