Whitehead torsion and the kernel of assembly
Oscar Harr
For a topological space that is homeomorphic to a finite simplicial complex, we prove that the Bartels--Nikolaus assembly functor has a fully faithful right adjoint. Using this, we…
The derived category of a locally compact space is rarely smooth
Oscar Harr
We show that the derived category of a locally compact Hausdorff space is smooth in the sense of non-commutative geometry if and only if is discrete and finite.
Compact sheaves on a locally compact space
Oscar Harr
We describe the compact objects in the -category of -valued sheaves on a hypercomplete locally compact Hausdorff space , for $\ma…
Twisted homology stability of O_n for valuation rings
Oscar Harr
In this article, we extend an argument of Vogtmann in order to show homology stability of the Euclidean orthogonal group when is a valuation ring subject to arithmetic…
Disordered arcs and Harer stability
Oscar Harr, Max Vistrup, Nathalie Wahl
We give a new proof of homological stability with the best known isomorphism range for mapping class groups of surfaces with respect to genus. The proof uses the framework of Randa…
