• NEIGHBORHOOD DAKSHAYANI INDICES

Abstract

Chemical Graph Theory is a branch of Mathematical Chemistry whose focus of interest is to finding graph invariants of molecular graphs. These correlate with chemical properties of the chemical compounds. In this paper, we propose new degree based topological descriptors such as first and second neighborhood Dakshayani indices, vertex neighborhood Dakshayani index, first and second hyper neighborhood Dakshayani indices of a graph and establish explicit formulas for these indices of line graphs of subdivision graphs of certain nanostructures.
