Randic and General Randic Indcies of Unicyclic Graphs
Journal Title: Saudi Journal of Engineering and Technology - Year 2017, Vol 2, Issue 7
Abstract
Abstract: Let a simple graph G is a connected graph. The General Randic Index GR(G) of a graph G is defined as GR(G) = ∑ (ρuρv )t ; uv ∈ E(G) where ρu and ρv are the degree of vertices u and v. If t = (-1)/( 2) ,then it is called Randic index which is defined as:- uv E(G) R(G) =∑ 1/√(ρ_(u ) ρ_v ) In this paper, we construct the Randic and General Randic Indcies of Alkanes and unicyclic graphs with application to cycloalkanes. Keywords: Randic , General Randic Indcies, Alkanes, Unicyclic Graphs and Cycloalkanes
