On potentially (K(,4) - e)-graphic sequences | Posted on:2003-04-03 | Degree:M.S | Type:Thesis | University:West Virginia University | Candidate:Niu, Jianbing | Full Text:PDF | GTID:2460390011984991 | Subject:Computer Science | Abstract/Summary: | | An n-term nonincreasing nonnegative integer sequence π = (d1, d2 ,,dn) is said to be graphic if it is the degree sequence of a simple graph G of order n, and such graph G is referred to as a realization of π. Let H be a simple graph. A graphic sequence π is said to be potentially H-graphic if it has a realization G containing H as a subgraph. In this paper, we characterize the potentially (K k − e)-graphic sequences for k = 4, 5, where (Kk − e) is the graph obtained from Kk by removing one edge. This characterization implies a theorem due to C. H. Lai [15] and a characterization of potentially C4-graphic sequences due to R.
