Extremal unicyclic and bicyclic graphs with respect to the -index

In the study of structure-dependency of the total -electron energy in 1972, it was shown that this energy depends on the degree based sum and , where is the degree of a vertex of under consideration molecular graph . Later on, the sum was named as first Zagreb index. An extensive research work has b...
