AbstractLet H be a real or complex infinite-dimensional Hilbert space. Then, for every closed ball B of H, there exists an affine continuous function T: H → H for which 〈T(x), x〉 is an interior point of {〈T(x), u〉: u ϵ B} for every x ϵ B. In fact, a stronger result concerning L2 is proved (Theorem 3)
