Codimension two index obstructions to positive scalar curvature
Bernhard Hanke, Daniel Pape, Thomas Schick
We derive a general obstruction to the existence of Riemannian metrics of positive scalar curvature on closed spin manifolds in terms of hypersurfaces of codimension two. The proof…

A Counterexample to a Conjecture about Positive Scalar Curvature
Daniel Pape, Thomas Schick
Conjecture 1 of Stanley Chang: "Positive scalar curvature of totally nonspin manifolds" asserts that a closed smooth manifold M with non-spin universal covering admits a metric of…
