Maximal vertex-connectivity of Sn,k

The class of star graphs is a popular topology for interconnection networks. However, it has certain deficiencies. A class of generalization of star graphs called (n, k)-star graphs was introduced by Chiang and Chen to address these issues. In this article we will consider the vertex-connectivity of the directed (n, k)-star graph, S n,k , given by Cheng and Lipman, [8], and show that it is maximally connected.
