The general sum-connectivity index of a graph G is defined as , where d u denotes the degree of vertex u in G, E(G) denotes the edge set of G, and Ξ± is a real number. We determine the maximum value for the general sum-connectivity indices of n-vertex trees and the corresponding extremal trees for Ξ±

Let T be a tree with n nodes from which edges are deleted interspersed with m on-line connectivity queries. Even and Shiloach gave an 0( n log n + m) algorithm to process edge deletion and m queries (Even and Shiloach, 1981). In this paper we present an O(n + m) algorithm for the same problem. @ 199
Let T(G) be the tree graph of a graph G with cycle rank r. Then K ( T ( G ) ) 3 m ( G ) -r, where K(T(G)) and m(G) denote the connectivity of T ( G ) and the length of a minimum cycle basis for G, respectively. Moreover, the lower bound of m ( G ) -r is best possible.
