Abstract:The i(G) denotes the Merrifield-Simmons index of graph G, it defined as the number ot the independent vertex sets of G; z( G) denotes the Hosoya index of the graph G, the m(G,k) is k - matching number of G, then the z(G) is the total number of m(G,k) (1 ≤ k≤ n / 2]), where n is the number of vertices of G. The Merrifield-Simmons index and Hosoya index of lollipop graph Ln,k are investigated and an order of Ln,k with respect to the Merrifield-Simmons and Hosoya index are provided in this paper.
Keywords:Merrifield-Simmons index  Hosoya index  lollipop graph
