The purpose of the present paper is to state a global
classification theorem for a class of proper Randers manifolds of
positive constant flag curvature.
The model for the classification is the unit sphere endowed with a Sasakian space form structure of constant -sectional curvature
Key Words: constant flag curvature, Finsler
isometry, Randers manifolds, Randers spheres, Sasakian space
forms.
