A Cuntz algebra approach to the classification of near-group categories

M Izumi - Proceedings of the 2014 Maui and, 2015 - projecteuclid.org
A. We classify C∗ near-group categories by using Vaughan Jones theory of subfactors and
the Cuntz algebra endomorphisms. Our results show that there is a sharp contrast between …

Projective symmetries of three-dimensional TQFTs

J Van Dyke - arXiv preprint arXiv:2311.01637, 2023 - arxiv.org
Quantum field theory has various projective characteristics which are captured by what are
called anomalies. This paper explores this idea in the context of fully-extended three …

spontaneous symmetry breaking occurs when certain symmetries of the Hamiltonian fail to …

The extended Haagerup fusion categories

P Grossman, S Morrison, D Penneys, E Peters… - arXiv preprint arXiv …, 2018 - arxiv.org
In this paper we construct two new fusion categories and many new subfactors related to the
exceptional Extended Haagerup subfactor. The Extended Haagerup subfactor has two even …

[图书][B] Fusion categories over non-algebraically closed fields

SC Sanford - 2022 - search.proquest.com
Much of the early work on Fusion Categories was inspired by physicists' desire for rigorous
foundations of topological quantum field theory. One effect of this was that base fields other …

The asaeda–haagerup fusion categories

P Grossman, M Izumi, N Snyder - Journal für die reine und …, 2018 - degruyter.com
The classification of subfactors of small index revealed several new subfactors. The first
subfactor above index 4, the Haagerup subfactor, is increasingly well understood and …

Type 𝐼𝐼 quantum subgroups of 𝔰𝔩_ {𝔑}. ℑ: Symmetries of local modules

C Edie-Michell - Communications of the American Mathematical Society, 2023 - ams.org
This paper is the first of a pair that aims to classify a large number of the type $ II $ quantum
subgroups of the categories $\mathcal {C}(\mathfrak {sl} _ {r+ 1}, k) $. In this work we classify …

Equivalences of graded categories

C Edie-Michell - arXiv preprint arXiv:1711.00645, 2017 - arxiv.org
We further the techniques developed by Etingof, Nikshych, and Ostrik in order to classify the
$\mathcal {C} $-based equivalences between two $ G $-graded extensions of $\mathcal {C} …

Lifting shadings on symmetrically self-dual subfactor planar algebras

Z Liu, S Morrison, D Penneys - Contemp. Math., 2020 - books.google.com
In this note, we discuss the notion of symmetric self-duality of shaded planar algebras, which
allows us to lift shadings on subfactor planar algebras to obtain Z/2Z-graded unitary fusion …

Invertible Fusion Categories

S Sanford, N Snyder - arXiv preprint arXiv:2407.02597, 2024 - arxiv.org
A tensor category $\mathcal {C} $ over a field $\mathbb {K} $ is said to be invertible if there's
a tensor category $\mathcal {D} $ such that $\mathcal {C}\boxtimes\mathcal {D} $ is Morita …
