Abstract
A new extension of the generalized topological indices (GTI) approach is carried out to represent 'simple' and 'composite' topological indices (TIs) in an unified way. This approach defines a GTIspace from which both simple and composite TIs represent particular subspaces. Accordingly, simple TIs such as Wiener, Balaban, Zagreb, Harary and Randić connectivity indices are expressed by means of the same GTI representation introduced for composite TIs such as hyperWiener, molecular topological index (MTI), Gutman index and reverse MTI. Using GTIspace approach we easily identify mathematical relations between some composite and simple indices, such as the relationship between hyperWiener and Wiener index and the relation between MTI and first Zagreb index. The relation of the GTIspace with the substructural cluster expansion of property/activity is also analysed and some routes for the applications of this approach to QSPR/QSAR are also given.
