  • Arithmetic-geometric index and its relations with geometric-arithmetic index
    Vujošević, Saša ...
    The arithmetic-geometric index ▫$(AG(G))$▫ was recently introduced as a modification of the well-known geometric-arithmetic index ▫$(GA(G))$▫. This paper reports results on searching for extremal ... ▫$AG$▫-graphs for various classes of simple graphs. Additionally, relations between these two indices are elaborated. Results on combinations ▫$AG+GA$▫, ▫$AG-GA$▫, ▫$AG \cdot GA$▫ and ▫$AG/GA$▫ are given. The paper is concluded with four conjectures that have been derived based on computer investigations.
