The Clifford Algebra Bundle on Loop Space
We construct a Clifford algebra bundle formed from the tangent bundle of the smooth loop space of a Riemannian manifold, which is a bundle of super von Neumann algebras on the loop space. We show that this bundle is in general non-trivial, more precisely that its triviality is obstructed by the tran...

| description | We construct a Clifford algebra bundle formed from the tangent bundle of the smooth loop space of a Riemannian manifold, which is a bundle of super von Neumann algebras on the loop space. We show that this bundle is in general non-trivial, more precisely that its triviality is obstructed by the transgressions of the second Stiefel-Whitney class and the first (fractional) Pontrjagin class of the manifold.

It is a pleasure to thank Achim Krause, David Roberts, Raphael Schmidpeter, and Konrad Waldorf for helpful discussions. I would also thank the anonymous referees for their suggestions, which improved the paper. I am indebted to SFB 1085 “Higher Invariants” for financial support. en Інститут математики НАН України Symmetry, Integrability and Geometry: Methods and Applications The Clifford Algebra Bundle on Loop Space Article published earlier |
