Abstract
Let G be a graph. The adjacent vertex sum polynomial is defined as S(G, x) = (G) i 0 ∑ n∆(G) – i. xα∆(G) – i where ∆(G) = max {deg v / v ∈ G}, n∆(G) – i is the sum of the number of adjacent vertices of all the vertices of degree ∆(G) – i and α∆(G) – i is the sum of the degree of adjacent vertices of all the vertices of degree ∆(G) – i. In this paper I find the
