Abstract :
In this paper we consider some (ALPHA, BETA)-metrics such as generalized Kropina, Matsumoto and F=(ALPHA, BETA)^2/ALPHA metrics, and obtain necessary and sufficient conditions for them to be Einstein metrics when BETA is a constant Killing form. Then we prove with this assumption that the mentioned Einstein metrics must be Riemannian or Ricci flat.
