Abstract
For a given graph H, a non-increasing sequence Ï=(d1,d2,â¦,dn) of nonnegative integers is said to be potentially H-graphic if there exists a realization of Ï containing H as a subgraph. The split graph Kr+Ks¯ on r+s vertices is denoted by Sr,s. In this paper, we give a Rao-type characterization for Ï to be potentially Sr,s-graphic. A simplification of this characterization is also presented.
