Some non-braided fusion categories of rank three
TJ Hagge, SM Hong - Communications in Contemporary …, 2009 - World Scientific
We classify all fusion categories for a given set of fusion rules with three simple object types.
If a conjecture of Ostrik is true, our classification completes the classification of fusion …

[HTML][HTML] Classifying substructures of extriangulated categories via Serre subcategories
H Enomoto - Applied Categorical Structures, 2021 - Springer
We give a classification of substructures (= closed subbifunctors) of a given skeletally small
extriangulated category by using the category of defects, in a similar way to the author's …

The low-dimensional structures formed by tricategories
We form tricategories and the homomorphisms between them into a bicategory, whose 2-
cells are certain degenerate tritransformations. We then enrich this bicategory into an …

Fusion categories via string diagrams
B Bartlett - Communications in Contemporary Mathematics, 2016 - World Scientific
We use the string diagram calculus to give graphical proofs of the basic results of Etingof,
Nikshych and Ostrik [On fusion categories, Ann. Math. 162 (2005) 581–642; arXiv …

Representations of fusion categories and their commutants
A Henriques, D Penneys - Selecta Mathematica, 2023 - Springer
A bicommutant category is a higher categorical analog of a von Neumann algebra. We study
the bicommutant categories which arise as the commutant C′ of a fully faithful …

Six-functor-formalisms and fibered multiderivators
F Hörmann - Selecta Mathematica, 2018 - Springer
We develop the theory of (op) fibrations of 2-multicategories and use it to define abstract six-
functor-formalisms. We also give axioms for Wirthmüller and Grothendieck formalisms …

Triangulated quotient categories
Y Liu, B Zhu - Communications in algebra, 2013 - Taylor & Francis
A notion of mutation of subcategories in a right triangulated category is defined in this article.
When (𝒵, 𝒵) is a 𝒟-mutation pair in a right triangulated category 𝒞, the quotient category 𝒵/𝒟 …

Traces on module categories over fusion categories
G Schaumann - Journal of Algebra, 2013 - Elsevier
We consider traces on module categories over pivotal fusion categories which are
compatible with the module structure. It is shown that such module traces characterise the …

[HTML][HTML] Triangulated quotient categories revisited
P Zhou, B Zhu - Journal of Algebra, 2018 - Elsevier
Extriangulated categories were introduced by Nakaoka and Palu by extracting the
similarities between exact categories and triangulated categories. A notion of mutation of …
