Abstract

Let MD(G, i) be the family of monophonic dominating sets of a graph G with cardinality i and let \md(G, i) = |MD(G, i)|. Then the monophonic domination polynomial MD(G, x) of G is defined as MD(G, x) = \sum_{i = \gamma_m(G)}^{p}  \md(G, i) x^i, where \gamma_m(G) is the monophonic domination number of G. In this paper we have determined the family of monophonic dominating sets of the path graph P_n with cardinality i. Also, the monophonic domination polynomial of the path graph is calculated and some properties of the coefficient \md(P_n, i) is discussed.
