Uniform twisted homological stability

J Miller, P Patzt, D Petersen… - arXiv preprint arXiv …, 2024 - arxiv.org
We prove a homological stability theorem for families of discrete groups (eg mapping class
groups, automorphism groups of free groups, braid groups) with coefficients in a sequence …

The reductive Borel–Serre compactification as a model for unstable algebraic K-theory

D Clausen, MØ Jansen - Selecta Mathematica, 2024 - Springer
Let A be an associative ring and M a finitely generated projective A-module. We introduce a
category RBS (M) and prove several theorems which show that its geometric realisation …

Higher-order representation stability and ordered configuration spaces of manifolds

J Miller, J Wilson - Geometry & Topology, 2019 - msp.org
Using the language of twisted skew-commutative algebras, we define secondary
representation stability, a stability pattern in the unstable homology of spaces that are …

-cells and mapping class groups

S Galatius, A Kupers, O Randal-Williams - Publications mathématiques de …, 2019 - Springer
We prove a new kind of stabilisation result,“secondary homological stability,” for the
homology of mapping class groups of orientable surfaces with one boundary component …

-cells and general linear groups of finite fields

S Galatius, A Kupers, O Randal-Williams - arXiv preprint arXiv:1810.11931, 2018 - arxiv.org
We prove new homological stability results for general linear groups over finite fields. These
results are obtained by constructing CW approximations to the classifying spaces of these …

Adjunction of roots, algebraic -theory and chromatic redshift

C Ausoni, HÖ Bayındır, T Moulinos - arXiv preprint arXiv:2211.16929, 2022 - arxiv.org
Given an $ E_1 $-ring $ A $ and a class $ a\in\pi_ {mk}(A) $ satisfying a suitable hypothesis,
we define a map of $ E_1 $-rings $ A\to A (\sqrt [m]{a}) $ realizing the adjunction of an $ m …

Unstable algebraic K-theory: homological stability and other observations

MØ Jansen - arXiv preprint arXiv:2405.02065, 2024 - arxiv.org
We investigate stability properties of the reductive Borel-Serre categories; these were
introduced as a model for unstable algebraic K-theory in previous work. We see that they …

Homological stability for Iwahori–Hecke algebras

R Hepworth - Journal of Topology, 2022 - Wiley Online Library
We show that the Iwahori–Hecke algebras H n H_n of type A n− 1 A_n-1 satisfy homological
stability, where homology is interpreted as an appropriate Tor group. Our result precisely …

On the edge of the stable range

R Hepworth - Mathematische Annalen, 2020 - Springer
We prove a general homological stability theorem for certain families of groups equipped
with product maps, followed by two theorems of a new kind that give information about the …
