Abstract

Let G be a simple connected graph with vertex set V(G) and edge set E(G). The Z ,qp index, for a real number for p z 0 , is defined as ¦  )( , , ),( ),( )( GEuv vuq vup qpqp ddM ddM GZZ , where p p v p u vup dd ddM 1 2 )()( ),( ¹ · © § and du is the degree of the vertex u. The Z ,qp index is a generalization of the geometric–arithmetic index. In this paper, some relations between Z ,qp , Randiü, and Zagreb indices are presented.
