Remarks on the paper "On Gromov's dihedral extremality and rigidity conjectures" by Jinmin Wang, Zhizhang Xie and Guoliang Yu
Christian Baer, Bernhard Hanke, Thomas Schick
The authors present a counterexample to an index calculation used in a recent paper on self‑adjoint extensions of Dirac‑type operators on manifolds with corners, showing that the c…
Contractibility of spaces of positive scalar curvature metrics with symmetry
Christian Baer, Bernhard Hanke
We show the contractibility of spaces of invariant Riemannian metrics of positive scalar curvature on compact connected manifolds of dimension at least two, with and without bounda…
K-cowaist of manifolds with boundary
Christian Baer, Bernhard Hanke
We extend the K-cowaist inequality to generalized Dirac operators in the sense of Gromov and Lawson and study applications to manifolds with boundary.
Scalar curvature rigidity of warped product metrics
Christian Baer, Simon Brendle, Bernhard Hanke +1
We show scalar-mean curvature rigidity of warped products of round spheres of dimension at least 2 over compact intervals equipped with strictly log-concave warping functions. This…
