Exclusive Sum Number of Incomplete Crown
Gao Xiu-lian · Journal of Dezhou University · 2007
The exclusive(integral) sum numbere(G)(ζ′(G))of G is the smallest number of isolated vertices which when added to G result in an exclusive integral sum graph.This paper has proved the exclusive integral sum number is equal to the exclusive sum number for all graph G;The graph Cn×K2 is called prism.It is called incomplete prism when we give a subdivision to Cn of prism;and this paper has proved the exclusive sum number of incomplete prism is 4 for all n≥3.
