Abstract :
The neighborhood first Zagreb index has recently been introduced
for characterizing the topological structure of molecular graphs. In
the present study, we characterize the graphs having minimum
neighborhood first Zagreb index in the class of unicyclic/bicyclic
graphs on vertices for every fixed integer .
