... ty−x t 2.1 exists for each x, y ∈ S and in this case E is said to be smooth. E is said to have a uniformly Frechet differentiable norm if the limit 2.1 is attained uniformly for x, y ∈ S and ... x, y ∈ S and in this case E is said to be uniformly smooth. It is well known that if E is uniformly smooth, then the duality map is norm-to-norm uniformly continuous on bounded subsets of E....
