RT Journal Article T1 On the Geometric-Arithmetic Index A1 Rodríguez García, José Manuel A1 Sigarreta Almira, José María AB The concept of geometric-arithmetic index was introduced in the chemical graph theory recently, but it has shown to be useful. The aim of this paper is to obtain new inequalities involving the geometric-arithmetic index GA1 and characterize graphs extremal with respect to them. In particular, we improve some known inequalities and we relate GA1 to other well known topological indices.
