Uniform Eberlein spaces and the finite axiom of choice
Marianne Morillon
We work in set-theory without choice $\ZF$. Given a closed subset of which is a bounded subset of ({\em resp.} such that ), we show…

Countable Choice and Compactness
Marianne Morillon
We work in set-theory without choice ZF. Denoting by AC(N) the countable axiom of choice, we show in ZF+AC(N) that the closed unit ball of a uniformly convex Banach space is compac…

A new proof of James' sup theorem
Marianne Morillon
We provide a new proof of James' sup theorem for (non necessarily separable) Banach spaces. One of the ingredients is the following generalization of a theorem of Hagler and Johnso…
