A short course on∞-categories

M Groth - Handbook of homotopy theory, 2020 - taylorfrancis.com
This chapter discusses non-technical account of some ideas in the theory of∞-categories,
as originally introduced by Boardman–Vogt in their study of homotopy-invariant algebraic …

[HTML][HTML] Simplicial structures in higher Auslander–Reiten theory

T Dyckerhoff, G Jasso, T Walde - Advances in Mathematics, 2019 - Elsevier
We develop a novel combinatorial perspective on the higher Auslander algebras of type A, a
family of algebras arising in the context of Iyama's higher Auslander–Reiten theory. This …

The additivity of traces in monoidal derivators

M Groth, K Ponto, M Shulman - Journal of K-theory, 2014 - cambridge.org
Motivated by traces of matrices and Euler characteristics of topological spaces, we expect
abstract traces in a symmetric monoidal category to be “additive”. When the category is …

Regular patterns, substitudes, Feynman categories and operads

M Batanin, J Kock, M Weber - arXiv preprint arXiv:1510.08934, 2015 - arxiv.org
We show that the regular patterns of Getzler (2009) form a 2-category biequivalent to the 2-
category of substitudes of Day and Street (2003), and that the Feynman categories of …

Fibered multiderivators and (co) homological descent

F Hörmann - arXiv preprint arXiv:1505.00974, 2015 - arxiv.org
The theory of derivators enhances and simplifies the theory of triangulated categories. In this
article a notion of fibered (multi-) derivator is developed, which similarly enhances fibrations …

[HTML][HTML] Abstract representation theory of Dynkin quivers of type A

M Groth, J Šťovíček - Advances in Mathematics, 2016 - Elsevier
We study the representation theory of Dynkin quivers of type A in abstract stable homotopy
theories, including those associated to fields, rings, schemes, differential-graded algebras …

Abstract tilting theory for quivers and related categories

M Groth, J Šťovíček - Annals of K-Theory, 2017 - msp.org
We generalize the construction of reflection functors from classical representation theory of
quivers to arbitrary small categories with freely attached sinks or sources. These reflection …

Revisiting the canonicity of canonical triangulations

M Groth - arXiv preprint arXiv:1602.04846, 2016 - arxiv.org
Stable derivators provide an enhancement of triangulated categories as is indicated by the
existence of canonical triangulations. In this paper we show that exact morphisms of stable …

[HTML][HTML] Tilting theory for trees via stable homotopy theory

M Groth, J Šťovíček - Journal of Pure and Applied Algebra, 2016 - Elsevier
We show that variants of the classical reflection functors from quiver representation theory
exist in any abstract stable homotopy theory, making them available for example over …
