Selection type results and fixed point property for affine bi-Lipschitz maps

Functional Analysis 2019-03-01 v1

Abstract

We obtain a refinement of a selection principle for (K,λ)(\mathcal{K}, \lambda)-wide-(s)(s) sequences in Banach spaces due to Rosenthal. This result is then used to show that if CC is a bounded, non-weakly compact, closed convex subset of a Banach space XX, then there exists a Hausdorff vector topology τ\tau on XX which is weaker than the weak topology, a closed, convex τ\tau-compact subset KK of CC and an affine bi-Lipschitz map T:KKT: K\to K without fixed points.
