A note on certain topological indices of the derived graphs of subdivision graphs

Abstract

In this note, we correct some errors in S. M. Hosamani et al. [TWMS J. App. Eng. Math., 6(2), (2016) pp. 324–332]. The derived graph [G]† of a graph G is the graph having the same vertex set as G, with two vertices of [G]†being adjacent if and only if their distance in G is two. Further, we compute generalized Randi´c, general Zagreb, general sum-connectivity, ABC, GA, ABC?, and GA? indices of the derived graphs of subdivision graphs.
