Maximum General Sum-Connectivity Index for Trees with Given Independence Number 1

Das, Xu and Gutman [MATCH Commun. Math. Comput. Chem. 70(2013) 301-314] proved that in the class of trees of order n and independence number s, the spur Sn,s maximizes both first and second Zagreb indices and this graph is unique with these properties. In this paper, we show that in the same class of trees T , Sn,s is the unique graph maximizing zeroth-order
