On the Nielsen realisation problem for cyclic groups of prime order
Christian Kremer
We solve the Nielsen realisation problem for high-dimensional aspherical manifolds in a new class of special cases. Mainly, we focus on actions of cyclic groups of prime order. A n…
Approximate Fibrations in Higher Topos Theory
Christian Kremer, Marco Volpe
The goal of this paper is to put the theory of approximate fibrations into the framework of higher topos theory. We define the notion of an approximate fibration for a general geom…
Semifree Isovariant Poincaré Spaces and the Gap Condition
Dominik Kirstein, Christian Kremer
We introduce the notion of a semifree isovariant -Poincaré space, a homotopical notion interpolating between semifree closed smooth -manifolds and the equivariant Poincaré sp…
Borel actions in nonpositively curved geometry and the Nielsen realisation problem
Christian Kremer
In this note, we record the proof of a theorem about the coincidence of genuine and homotopy fixed points for isometric group actions on complete Riemannian manifolds with nonposit…
Poincaré Duality Pairs of -Categories
Andrea Bianchi, Kaif Hilman, Dominik Kirstein +1
We introduce a notion of Poincaré duality for pairs of -categories, extending Poincaré-Lefschetz duality for pairs of spaces. This categorical extension yields an efficient…
A twisted Bass-Heller-Swan decomposition for localising invariants
Dominik Kirstein, Christian Kremer
We generalise the classical Bass-Heller-Swan decomposition for the K-theory of (twisted) Laurent algebras to a splitting for general localising invariants of certain categories of…
