SECOND ORDER AND SECOND SUM CONNECTIVITY INDICES OF TETRATHIAFULVALENE DENDRIMERS. Authors: . |
||||||
Abstract: The m-order connectivity index is an extension of the Randic (simple) connectivity index that counts the connectivity of all paths of length m in G. The m -sum connectivity index changes the multiplication with addition, in the above index. A dendrimer is a hyperbranched molecule built up from branched units called monomers. In this paper, the 2-order connectivity and 2-sum connectivity indices of an infinite family of tetrathiafulvalene dendrimer are computed. Key words: Randic connectivity index, Sum-connectivity index, Dendrimers. |
