Bond additive modelling 10. Upper and lower bounds of bond incident degree indices of catacondensed fluoranthenes

Bond incident degree index is a descriptor that is calculated as the sum of the bond contributions such that each bond contribution depends solely on the degrees of its incident vertices (e.g. Randić index, Zagreb index, modified Zagreb index, variable Randić index, atom-bond connectivity index, augmented Zagreb index, sum-connectivity index, many Adriatic indices, and many variable Adriatic indices). In this paper we find tight upper and lower bounds for bond incident degree index for catacondensed fluoranthenes with given number of hexagons.
