چکیده

The m-order connectivity index ) (g m? of a graph g is ????1 2 11 2 1... ...1) (m i i imv v vi i imd d dg ? where 12 1...m ii idd d ?runs over all paths of length m in g and id denotes the degree of vertex iv . also, ???? ? ??1 2 11 2 1... ...1) (m i i imv v vi i imsd d dg x is its m-sum connectivity index. a dendrimer is an artificially manufactured or synthesized molecule built up from branched units called monomers. in this paper, the 4-order connectivity and 4-sum connectivity indices of tetrathiafulvalene dendrimers are computed.
