Fourth Order and Fourth Sum Connectivity Indices of Polyphenylene Dendrimers

Nabeel E. Arif, Roslan Hasni and Saeid Alikhani

Abstract:
The m-order connectivity index mχ(G) of a graph G is where, runs over all paths of length m in G and di denotes the degree of vertex vi. Also is its m-sum connectivity index. A dendrimer is an artificially manufactured or synthesized molecule built up from branched units called monomers. In this study, the 4-connectivity and 4-sum connectivity indices of an infinite family of polyphenylene dendrimer are computed.
