Minimizing the General Atom-Bond Sum-Connectivity Index of Unicyclic Graphs

Journal of applied mathematics and computing. International journal
This paper gives the characterization of those graphs that minimize the general atom- bond sum-connectivity index ABS ȷ among all fixed-order unicyclic graphs of a given maximum degree for 1 ≤ ȷ < 2. It is also proved that the cycle graph uniquely minimizes the aforementioned index in the class of all fixed-order unicyclic graphs.
