Stable $2$ -systoles, scalar curvature and spin $^{c}$ comass bounds

Simone Cecchini, Sven Hirsch, Rudolf Zeidler

We prove a sharp stable $2$ -systolic inequality for complex projective space under the scalar curvature lower bound of the normalized Fubini-Study metric. If $M$ is diffeomorphic t…

The degree condition in Llarull's theorem on scalar curvature rigidity

Christian Baer, Rudolf Zeidler

Llarull's scalar curvature rigidity theorem states that a 1-Lipschitz map $f : M \to S^{n}$ from a closed connected Riemannian spin manifold $M$ with scalar curvature $\mathrm{scal}\ge…

Duality pairings with the analytic structure group

Christopher Wulff, Rudolf Zeidler

We construct a slant product $S_{p}^{G \times H} (X \times Y) \otimes K_{- q} (c ˉ^{red} Y ⋊ H) \to K_{p - q} (C_{G}^{*} X)$ on…
