The Exclusive Integral Sum Number of Incomplete Prism
Gao Xiu-lian · Journal of Dezhou University · 2006
The exclusive(integral) sum number e(G)(ζ′(G)) of G is the smallest number of isolated vertices which when added to G result in an exclusive(integral) sum graph.C_n×K_2 is called prism. This paper gives a definition of incomplete prism,and has proved the exclusive integral sum number of incomplete prism is 4 for all n≥3.
