Abstract

In this paper, the hyper-Zagreb coindex of the union, Cartesian product, composition and corona product of graphs are computed. The hyper-Zagreb coindex of the union, Cartesian product and composition of graphs correct some errors in Veylaki et al. (J Appl Math Comput, doi:10.1007/s12190-015-0872-z, 2015).
