Abstract

The Ivanciuc-Balaban operator of a graph G is defined as J(M,G) =M/mu+1 (vivj is an element of E(G))Sigma (M(i) . M(j))(-v2) where M is its molecular matrix with positive row-sums, m is the number of edges, p is the cyclomatic number, M(i) is the i-th row sum of M and the summation goes over all edges from the edge-set E(G). Here we consider the reciprocal Balaban index (r)J(G) = J(RD,G) and the reverse Balaban index J(r)(G)=J(RW,G), where RD and RW are respectively the reciprocal distance matrix and the reverse Wiener matrix of G. Various lower and upper bounds for these two types of Balaban-like indices are reported.
