On The Reformulated Zagreb Coindex
Abstract
The reformulated Zagreb coindex of G is specied the degrees di The reformulated Zagreb coindex of G is specied the degrees di and dj . This paper includes some inequalities for the reformulated Zagreb index and reformulated Zagreb coindex. Also, some bounds are reported consepting the eigenvalues and complement of eigenvalues. and dj .
