Dakshayani Indices of Derived Graphs of Subdivision of Crown Graph

Abstract

In theoretical Chemistry, the physico-chemical properties of chemical compounds are often modeled by means of molecular graphbased structure descriptors, which are also referred to as topological indices. The derived graph of a simple graph ????, denoted by ????+, is the graph having the same vertex set of???? and two vertices are adjacent if and only if their distance in ???? is two. In this paper, we compute generalized,Dakshayani, first and second neighborhood Dakshayani, indices, first and second hyper neighbourhood. Dakshayani indices, the minus and square neighbourhoodDakshayani indices and ????????- neighbourhood Dakshayani indices of the derived graph of subdivison graph of a crown graph.
