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.]]>Ashrafi, A.R. and P. Nikzad,20094269273Ahmadi, M.B. and M. Sadeghimehr,20094639643Chen, S. and J. Yang,20116223225Kier, L.B. and L.H.
