Abstract

A connected graph G is said to be cactus if no two cycles of G have any common edge. The present note is devoted to developing some extremal results for the zeroth-order general Randić index of cactus graphs and finding some sharp bounds on this index. Keywords: Topological index, Cactus graph, Zeroth-order general Randić index

Keywords:
