Abstract
A dominating set D of a graph G = (V, E) is a split dominating set if the induced subgraph 〈V-D〉 is disconnected. The split domination number γs(G) is the minimum cardinality of a split dominating set of G. The set of vertices is a γs- set if it is split dominating set with γs(G). In this paper, we obtain the total number of γs-sets, the Partially Balanced Incomplete Block (PBIB)-Designs on γs-sets of certain jump sizes of Circulant graphs with m-association schemes for 1≤ m≤⌊ p/2⌋.
