Randic index of various classes of graphs formed on the basis of some graph combinations
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 9
Abstract
The Randic index R(G) of a graph G=(V,E) is defined as follows Here du and dv are the degrees of vertices u and v respectively. In this paper, we give explicit computing formulae for various classes of graphs formed on the basis of two types of Combinations A and B. Moreover, we introduce a relationship between the randic index of combined graphs GA ,GB and first Zagreb index.
