The second hyper-zagreb indices and coindices of disjunction and symmetric difference of graphs

Author(s):

Abdu Alameri, Mohammed Alsharafi and Hanan Ahmed

Abstract:

A topological index is a numerical descriptor of a molecule, based on a certain topological feature of the corresponding molecular graph. In this paper, we explore here some basic mathematical properties and present explicit formulas for the second Hyper-Zagreb coindex under graph operations (disjunction and symmetric difference).
