摘要:
Bonchev and Kier proposed sometime ago the extended connectivity indices which may be used in structure-property-activity modeling. We establish some properties, mainly various lower and upper bounds for the first extended zeroth-order connectivity index (0)chi (1) and the first extended first-order connectivity index (1)chi (1).
