Almost square dual Banach spaces
Original language description
We show that finite dimensional Banach spaces fail to be uniformly non locally almost square. Moreover, we construct an equivalent almost square bidual norm on l(infinity). As a consequence we get that every dual Banach space containing c(0) has an equivalent almost square dual norm. Finally we characterize separable real almost square spaces in terms of their position in their fourth duals. (C) 2020 The Authors. Published by Elsevier Inc.
