Sažetak
The general sum-connectivity index of a graph G is defined as X alpha(G) = Sigma edges (d(u) + d(v))(alpha), where d(u) denotes the degree of vertex u in G and a is alpha real number. In this report, we determine the minimum and the second minimum values of the general sum-connectivity indices of n-vertex unicyclic graphs for non-zero alpha >= -1, and characterize the corresponding extremal graphs.
