Let A be a simple, unital, finite, and exact C-algebra which absorbs the Jiang-Su algebra Z tensorially. We prove that the Cuntz semigroup of A admits a complete order embedding into an ordered semigroup which is obtained from the Elliott invariant in a functorial manner. We conjecture that this embedding is an isomorphism, and prove the conjecture in several cases. In these same cases — Z-stab...

One of the most central problems for 21st century mathematical physics is the question: “how can we mathematically formalize the notion of a non-perturbative quantum field theory?” Formulations of aspects of quantum field theory developed by mathematicians (e.g. [Seg88], [Ati88], [FLM89], [Lur09], [BD04]) have generated conceptual frameworks for problems in mathematics far removed from physics....

Experiments with polarized neutrons at high energy have interested me recently for at least five reasons as follows: (i) Our Michigan group has over the past decade evolved a program of hadronic physics with neutron beams at the Bevatron, the ZGS, the AGS, and at FNAL so that we feel quite familiar with the problems and 1 techniques in this area (2) The Argonne ZGS has discussed plans to accele...
