Abstract EN
Let G=(V,E) be a simple graph.
A set S⊆V is a dominating set of G, if every vertex in V\S is adjacent to at least one vertex in S.
Let ?ni be the family of all dominating sets of a path Pn with cardinality i, and let d(Pn,j)=|?nj|.
In this paper, we construct ?ni, and obtain a recursive formula for d(Pn,i).
Using this recursive formula, we consider the polynomial D(Pn,x)=∑i=⌈n/3⌉nd(Pn,i)xi, which we call domination polynomial of paths and obtain some properties of this polynomial.
