# Domination Polynomial

Let be the number of dominating sets of size in a graph , then the domination polynomial of in the variable is defined as

where is the (lower) domination number of (Kotek et al. 2012, Alikhani and Peng 2014).

is multiplicative over connected components (Alikhani and Peng 2014).

Precomputed dominations polynomials for many named graphs in terms of a variable and in the Wolfram Language as GraphData[graph, "DominationPolynomial"][x].

The following table summarizes closed forms for the domination polynomials of some common classes of graphs (cf. Alikhani and Peng 2014).

The following table summarizes the recurrence relations for domination polynomials for some simple classes of graphs.
