Incomplete Tambara functors

A Blumberg, M Hill - Algebraic & Geometric Topology, 2018 - msp.org
For a “genuine” equivariant commutative ring spectrum R, π 0 (R) admits a rich algebraic
structure known as a Tambara functor. This algebraic structure mirrors the structure on R …

Real topological Hochschild homology

E Dotto, K Moi, I Patchkoria, SP Reeh - Journal of the European …, 2020 - ems.press
This paper interprets Hesselholt and Madsen's real topological Hochschild homology functor
THR in terms of the multiplicative norm construction. We show that THR satisfies cofinality …

Koszul Resolutions over Free Incomplete Tambara Functors for Cyclic -Groups

D Mehrle, JD Quigley, M Stahlhauer - arxiv preprint arxiv:2407.18382, 2024 - arxiv.org
In equivariant algebra, Mackey functors replace abelian groups and incomplete Tambara
functors replace commutative rings. In this context, we prove that equivariant Hochschild …

Loday Constructions of Tambara functors

A Lindenstrauss, B Richter, F Zou - arxiv preprint arxiv:2401.04216, 2024 - arxiv.org
Building on work of Hill, Hoyer and Mazur we propose an equivariant version of a Loday
construction for $ G $-Tambara functors where $ G $ is an arbitrary finite group. For any finite …

Freeness and equivariant stable homotopy

MA Hill - Journal of Topology, 2022 - Wiley Online Library
We introduce a notion of freeness for RO RO‐graded equivariant generalized homology
theories, considering spaces or spectra EE such that the RR‐homology of EE splits as a …

An introduction to algebraic models for rational G-spectra

D Barnes, M Kedziorek - arxiv preprint arxiv:2004.01566, 2020 - arxiv.org
The project of Greenlees et al. on understanding rational G-spectra in terms of algebraic
categories has had many successes, classifying rational G-spectra for finite groups, SO (2) …

Equivariant cohomology for cyclic groups

S Basu, P Dey - arxiv preprint arxiv:2403.00362, 2024 - arxiv.org
In this paper, we compute the $ RO (C_n) $-graded coefficient ring of equivariant
cohomology for cyclic groups $ C_n $, in the case of Burnside ring coefficients, and in the …

Real topological Hochschild homology via the norm and Real Witt vectors

G Angelini-Knoll, T Gerhardt, M Hill - arxiv preprint arxiv:2111.06970, 2021 - arxiv.org
We prove that Real topological Hochschild homology can be characterized as the norm from
the cyclic group of order $2 $ to the orthogonal group $ O (2) $. From this perspective, we …

Reflexive homology and involutive Hochschild homology as equivariant Loday constructions

A Lindenstrauss, B Richter - arxiv preprint arxiv:2407.20082, 2024 - arxiv.org
For associative rings with anti-involution several homology theories exists, for instance
reflexive homology as studied by Graves and involutive Hochschild homology defined by …

On the -local equivariant sphere

PJ Bonventre, BJ Guillou, NJ Stapleton - arxiv preprint arxiv:2204.03797, 2022 - arxiv.org
Equivariant complex $ K $-theory and the equivariant sphere spectrum are two of the most
fundamental equivariant spectra. For an odd $ p $-group, we calculate the zeroth homotopy …
