Graph polynomials serve as robust algebraic encodings of the intricate combinatorial properties inherent to graphs. At the heart of this discipline lies the Tutte polynomial, an invariant that not ...

Abstract. Let 𝐼(𝐺;𝑥) denote the independence polynomial of a graph 𝐺. In this paper we study the unimodality properties of 𝐼(𝐺;𝑥) for some composite graphs 𝐺. Given two graphs 𝐺₁ and 𝐺₂, let ...

Abstract.Let 𝐺 be a simple graph of order 𝑛. The domination polynomial of 𝐺 is the polynomial D(G,x)= ∑ i=0 n d(G,i) x i , where 𝑑(𝐺,𝑖) is the number of dominating sets of 𝐺 of size 𝑖. Let 𝑛 ...
