Reciprocal Combinatorial Matrices

The reciprocal combinatorial matrices, the reciprocal distance-delta matrix CM- and the reciprocal distance-path matrix CM, are matrices whose entries are 

Hyper-Harary indices are defined for the reciprocal distance-path matrix (Diudea, 1997 Todeschini and Consonni, 2000,2009) and were used in a structure-property modeling of lower alkanes and branched and unbranched cycloalkanes (Trinajstid

The reciprocal combinatorial matrices and CM- of T2 (see Figure 2.19) and G, (see strnctnre A in Fignre 2.1), based on the corresponding combinatorial matrices, given above, are as follows ...
