A convexity of functions on convex metric spaces of Takahashi and applications

We show that Takahashi's idea of convex structures on metric spaces is a natural generalization of convexity in normed linear spaces and Euclidean spaces in particular. Then we introduce a concept of convex structure based convexity to functions on these spaces and refer to it as W-convexity. W...
