چکیده
|
The variable sum exdeg index of a graph g is defined as seia(g)=∑u∈v(g)dg(u)adg(u), where a≠1 is a positive real number, dg(u) is the degree of a vertex u∈v(g). in this paper, we characterize the graphs with the extremum variable sum exdeg index among all the graphs having a fixed number of vertices and cut edges, for every a>1.
