Classification of Grothendieck rings of complex fusion categories of multiplicity one up to rank six

Z Liu, S Palcoux, Y Ren - Letters in Mathematical Physics, 2022 - Springer
This paper classifies the Grothendieck rings of complex fusion categories of multiplicity one
up to rank six. Among 72 possible fusion rings, 25 ones are filtered out by using …

Quantum fourier analysis

A Jaffe, C Jiang, Z Liu, Y Ren… - Proceedings of the …, 2020 - National Acad Sciences
Quantum Fourier analysis is a subject that combines an algebraic Fourier transform (pictorial
in the case of subfactor theory) with analytic estimates. This provides interesting tools to …

On low rank fusion rings

G Vercleyen, JK Slingerland - Journal of Mathematical Physics, 2023 - pubs.aip.org
We present a method to generate all fusion rings of a specific rank and multiplicity. This
method generated exhaustive lists of fusion rings up to order 9 for several multiplicities. We …

Galois orbits of TQFTs: symmetries and unitarity

M Buican, R Radhakrishnan - Journal of High Energy Physics, 2022 - Springer
A bstract We study Galois actions on 2+ 1D topological quantum field theories (TQFTs),
characterizing their interplay with theory factorization, gauging, the structure of gapped …

Burnside type results for fusion rings

S Burciu, S Palcoux - arXiv preprint arXiv:2302.07604, 2023 - arxiv.org
In this paper, we extend a classical vanishing result of Burnside from the character tables of
finite groups to the character tables of commutative fusion rings, or more generally to a …

On odd-dimensional modular tensor categories

A Czenky, J Plavnik - Algebra & Number Theory, 2022 - msp.org
We study odd-dimensional modular tensor categories and maximally nonself dual (MNSD)
modular tensor categories of low rank. We give lower bounds for the ranks of modular tensor …

Quantum smooth uncertainty principles for von Neumann bi-algebras

L Huang, Z Liu, J Wu - Quantum Topology, 2024 - ems.press
In this article, we prove various smooth uncertainty principles on von Neumann bi-algebras,
which unify a number of uncertainty principles on quantum symmetries, such as subfactors …

Interpolated family of non-group-like simple integral fusion rings of Lie type

Z Liu, S Palcoux, Y Ren - International Journal of Mathematics, 2023 - World Scientific
This paper is motivated by the quest of a non-group irreducible finite index depth 2 maximal
subfactor. We compute the generic fusion rules of the Grothendieck ring of Rep (PSL (2, q)) …

Triangular prism equations and categorification

Z Liu, S Palcoux, Y Ren - arXiv preprint arXiv:2203.06522, 2022 - arxiv.org
We introduce the triangular prism equations for fusion categories, which turn out to be
equivalent to the pentagon equations in the spherical case (up to a change of basis), but …

Compact hypergroups from discrete subfactors

M Bischoff, S Del Vecchio, L Giorgetti - Journal of Functional Analysis, 2021 - Elsevier
Conformal inclusions of chiral conformal field theories, or more generally inclusions of
quantum field theories, are described in the von Neumann algebraic setting by nets of …
