Abstract
The Harary index and the Wiener index are two well-studied topological indices in chemical graph theory. Quite recently, the graphs attaining the minimum value of the product of the Harary and Wiener indices were characterized in [E. Azjargal, B. Horoldagva,
I. Gutman, Minimum of product of Wiener and Harary indices, MATCH Commun. Math. Comput. Chem.92 (2024) 65-71] over the class of all connected graphs of a fixed order and size. The present paper provides a
generalization, involving Wiener-type topological indices and their reciprocals, of the aforementioned result.
