Twisted K-theory and obstructions against positive scalar curvature metrics
Published online by Cambridge University Press: 17 April 2014
Abstract
We decompose θ(M), the twisted index obstruction to a positive scalar curvature metric for closed 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 a closed orientable enlargeable manifold with spin universal cover.
