ON BOUNDS FOR DEGREE BASED INDICES OF A GRAPH

Let G be a simple graph. In this talk, we provide some inequalities between energy and the Sombor index and the Randić index of G. Also, we state an upper bound for the degree based indices of G in terms of its size and the smallest absolute value of the eigenvalues of the matrices corresponding to these indices. ۲۰۲۰ Mathematics Subject Classification.
