Topological indices of nanotubes are numerical descriptors that are derived from graph of chemical compounds. Such indices based on the distances in graph are widely used for establishing relationships between the structure of nanotubes and their physico-chemical properties. The Szeged index is obtained as a bond additive quantity where bond contributions… (More)

The Sezegd index of a graph G is defined as Sz(G)= e∈E(G) n u (e)n v (e), where n u (e) is the number of vertices of G lying closer to u than to v, n v (e) is the number of vertices of G lying closer to v than to u and the summation goes over all edges e = uv of G. Also Balaban index of G is defined by J(G) = m (µ + 1) uv∈E(G) [d(u)d(v)] −0.5 , where d(v) =… (More)

For a finite group G, #Cent(G) denotes the number of central-izers of its elements. A group G is called n-centralizer if #Cent(G) = n, and primitive n-centralizer if #Cent(G) = #Cent G Z(G) = n. The first author in [1], characterized the primitive 6-centralizer finite groups. In this paper we continue this problem and characterize the primitive… (More)
