Torsion Obstructions to Positive Scalar Curvature
Misha Gromov, Bernhard Hanke
We study obstructions to the existence of Riemannian metrics of positive scalar curvature on closed smooth manifolds arising from torsion classes in the integral homology of their…
Coarse topology, enlargeability, and essentialness
B. Hanke, D. Kotschick, J. Roe +1
Using methods from coarse topology we show that fundamental classes of closed enlargeable manifolds map non-trivially both to the rational homology of their fundamental groups and…
Dissolving four-manifolds and positive scalar curvature
B. Hanke, D. Kotschick, J. Wehrheim
We prove that many simply connected symplectic four-manifolds dissolve after connected sum with only one copy of . For any finite group G that acts freely on the…
Poincare duality in P.A. Smith theory
Ch. Allday, B. Hanke, V. Puppe
Let G=S^1, G=Z/p or more generally G be a finite p group, where p is an odd prime number. If G acts on a space whose cohomology ring satisfies Poincare duality (with appropriate co…
