Minimum general sum-connectivity index of unicyclic graphs
Journal of Mathematical Chemistry, 2010The 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 ...

RELATION BETWEEN GENERAL RANDIC INDEX AND ´ GENERAL SUM CONNECTIVITY INDEX
South East Asian J. of Mathematics and Mathematical Sciences, 2022The general Randi´c index is the sum of weights of (d(u).d(v))k for every edge uv of a molecular graph G. On the other hand general Sum-Connectivity index is the sum of the weights (d(u) + d(v))k for every edge uv of G, where k is a real number and d(u) is the degree of vertex u.

On general sum-connectivity index
Journal of Mathematical Chemistry, 2009We report some properties especially lower and upper bounds in terms of other graph invariants for the general sum-connectivity index which generalizes both the ordinary sum-connectivity index and the first Zagreb index. Additionally, we give the Nordhaus-Gaddum-type result for the general sum-connectivity index.
