Projective change between two classes of (α,β)(α,β)-metrics

In this paper, we find equations to characterize projective change between (α,β)(α,β)-metric F=(α+β)2α and Randers metric F¯=α¯+β¯ on a manifold with dimension n⩾3n⩾3, where α   and α¯ are two Riemannian metrics, β   and β¯ are two nonzero one forms. Moreover, we consider this projective change when F has some special curvature properties.
