abstract

  • Recently, the arithmetic-geometric index (AG) was introduced, inspired by the well-known and studied geometric-arithmetic index (GA). In this work, we obtain new bounds on the arithmetic-geometric index, improving upon some already known bounds. In particular, we show families of graphs where such bounds are attained.
