ALIZADEHHakim Sabzevari University, Sabzevar, IranJournal Article20140504Let G be a simple graph with vertex set V(G) {v1,v2 ,...vn} . For every vertex i v , ( ) i v represents the degree of vertex i v . The h-th order of Randić index, h R is defined as the sum of terms 1 2 1 1 ( ), ( )... ( ) i i ih v v v over all paths of length h contained (as sub graphs) in G . In this paper , some bounds for higher Randić index and a method for computing the higher Randic index of a simple graph is presented . Also, the higher Randić index of coronene/circumcoronene is computed.http://ijmc.kashanu.ac.ir/article_5301_2937bfe5de90a364cc45426a78b04b0b.pdf
