Twisted K-theory and obstructions against positive scalar curvature metrics
Pennig, Ulrich
Research article (journal) | Peer reviewedAbstract
We decompose the twisted index obstruction θ(M) against positive scalar curvature metrics for oriented manifolds with spin universal cover into a pairing of a twisted K-homology with a twisted K-theory class and prove that θ(M) does not vanish if M is an orientable enlargeable manifold with spin universal cover.
