Scalar Curvature Rigidity for Products of convex Hypersurfaces and even dimensional Manifolds
Georg Frenck, Thomas Schick, Lukas Schönlinner
We give a proof of scalar curvature rigidity in the spirit of Llarull and Goette-Semmelmann for products of strictly convex hypersurfaces in Euclidean space and nonnegatively curve…
Abstract cone operators and Lipschitz rigidity for scalar curvature on singular manifolds
Simone Cecchini, Bernhard Hanke, Thomas Schick +1
Using the index theory for twisted Dirac operators acting on sections of Lipschitz bundles over non-compact manifolds, we prove Llarull-type comparison results in scalar curvature…
Topological Complexity of symplectic CW-complexes
Luca Sandrock, Thomas Schick
A cohomology class u of a topological space X is atoroidal if its pullback to the torus vanishes for every map from a torus to X. Furthermore, X is atoroidally symplectic if there…
Coarse Baum-Connes and warped cones: failure of surjectivity in odd degree
Christos Kitsios, Thomas Schick, Federico Vigolo
We prove a conjecture of Roe by constructing unified warped cones that violate the coarse Baum-Connes conjecture. Interestingly, the reason for this is probably not what Roe expect…
Stolz Positive Scalar Curvature Structure Groups, Proper Actions and Equivariant 2-Types
Massimiliano Puglisi, Thomas Schick, Vito Felice Zenobi
In this note, we study equivariant versions of Stolz' -groups, the positive scalar curvature structure groups , for proper actions of discrete groups . W…
Approximating Spectral invariants of Harper operators on graphs II
Varghese Mathai, Thomas Schick, Stuart Yates
We study Harper operators and the closely related discrete magnetic Laplacians (DML) on a graph with a free action of a discrete group, as defined by Sunada. The spectral density f…
