“…It is easily verified that ball proximinality implies proximinality. [1] Best approximative properties of hyperplanes or subspaces in general, of Banach spaces are closely related to structure of the unit ball and its exposed faces and study of geometric structure of the unit ball in view of this link, is not new [2]. We also refer to [3], [4], [5], [7] and Proposition 1 of [10] in this regard.…”
