%0 Journal Article %T Generalized Geodesic Convexity on Riemannian Manifolds %J Mathematics | An Open Access Journal from MDPI %D 2019 %R https://doi.org/10.3390/math7060547 %X We introduce log-preinvex and log-invex functions on a Riemannian manifold. Some properties and relationships of these functions are discussed. A characterization for the existence of a global minimum point of a mathematical programming problem is presented. Moreover, a mean value inequality under geodesic log-preinvexity is extended to Cartan-Hadamard manifolds. View Full-Tex %U https://www.mdpi.com/2227-7390/7/6/547
