WebAs a byproduct, we show that the Krein- Smulian theorem for the dual of a separable Banach space (Theorem 2.7 below) is provable in ACA 0(Theorem 4.14 below). We conjecture that the Krein- Smulian theorem for the dual of a separable Banach space is actually provable in the weaker system WKL 0. WebAuthors and Affiliations.

WebIn arbitrary Banach spaces, the norm-fragmentability assumption on H is shown to be sufficient for the last property to hold. A new proof to the following result is given: if a Banach space does not contain a copy of `1[0, 1], then the Krein-Smulian theorem holds for every topology τ induced by a norming set of functionals.
