Measurable selector in Kadison's carpenter's theorem

Functional Analysis 2018-03-12 v1

Abstract

We show the existence of a measurable selector in Carpenter's Theorem due to Kadison. This solves a problem posed by Jasper and the first author. As an application we obtain a characterization of all possible spectral functions of shift-invariant subspaces of L2(Rd)L^2(\mathbb R^d) and Carpenter's Theorem for type I_\infty von Neumann algebras.
