Extremal graphs for α-index
Let N(G) be the number of vertices of the graph G. Let Pl(Bi) be the tree obtained of the path Pl and the trees B1,B2,...,Bl by identifying the root vertex of Bi with the i-th vertex of Pl. Let V m n = {Pl(Bi) : N(Pl(Bi)) = n;N(Bi) ≥ 2;l ≥ m}. In this paper, we determine the tree that has the larges...
