A class of prime fusion categories of dimension $2^N$

  author={Jingcheng Dong and Sonia Natale and Hua Sun},
  journal={arXiv: Quantum Algebra},
We study a class of strictly weakly integral fusion categories $\mathfrak{I}_{N, \zeta}$, where $N \geq 1$ is a natural number and $\zeta$ is a $2^N$th root of unity, that we call $N$-Ising fusion categories. An $N$-Ising fusion category has Frobenius-Perron dimension $2^{N+1}$ and is a graded extension of a pointed fusion category of rank 2 by the cyclic group of order $\mathbb Z_{2^N}$. We show that every braided $N$-Ising fusion category is prime and also that there exists a slightly…

Weakly integral fusion categories of low dimensions

In this paper, we prove that fusion categories of FrobeniusPerron dimensions 84 and 90 are either solvable or group-theoretical. Together with the results in the literature, we obtain that every

On extensions of two families of Tambara–Yamagami categories

Abstract In this paper, we study the extension of a Tambara–Yamagami category which is of type or where p is a prime number. When the extensions are braided, we further classify the former one in the

Irrational braided generalized near-groups

We classify braided generalized near-group fusion categories whose global dimension is not an integer; there are exactly two up to Grothendieck equivalence and taking products with braided pointed



On the classification of certain fusion categories

We advance the classification of fusion categories in two directions. Firstly, we completely classify integral fusion categories -- and consequently, semi-simple Hopf algebras -- of dimension $pq^2$,

On fusion categories

Using a variety of methods developed in the literature (in particular, the theory of weak Hopf algebras), we prove a number of general results about fusion categories in characteristic zero. We show

Group categories and their field theories

A group-category is an additively semisimple category with a monoidal product structure in which the simple objects are invertible. For example in the category of representations of a group,

Fusion categories and homotopy theory

We apply the yoga of classical homotopy theory to classification problems of G-extensions of fusion and braided fusion categories, where G is a finite group. Namely, we reduce such problems to

Nilpotent fusion categories

Faithful simple objects, orders and gradings of fusion categories

We establish some relations between the orders of simple objects in a fusion category and the structure of its universal grading group. We consider fusion categories which have a faithful simple

Classifying fusion categories ⊗ -generated by an object of small Frobenius–Perron dimension

The goal of this paper is to classify fusion categories C which are ⊗ -generated by an object X of Frobenius–Perron dimension less than 2, with the additional mild assumption that the adjoint
