Uniform convexity and focal points
In this paper the uniform convexity as well as stıict uniform convexity have been defined for Riemannian manifolds. Necessary and sufficient conditions are established for a Riemannian manifold without conjugate points to be free from focal points in terms of the uniform convexity concept.
