Abstract
Let G be a simple graph of order n . The domination polynomial of G is the polynomial n i
i G
D(G, x) = d(G, i)x
= ( )
, where
d(G, i) is the number of dominating sets of G of size i and (G) is the domination number of G . The number of
dominating sets of a graph G is D(G,1) . In this paper we consider cactus chains with triangular and square blocks and
study their domination polynomials..
Keywords
Domination polynomial, Dominating sets, Cactus.
