Classification of some $Z /2 Z \times Z /2 Z$ -quadratic fusion categories of rank 6

Yue Meng, Zhiqiang Yu

A fusion category $C$ is said to be $Z /2 Z \times Z /2 Z$ -quadratic if the group $G (C)$ of invertible objects is isomorphic to $…

On the structure of Witt groups and minimal extension conjecture

Theo Johnson-Freyd, Victor Ostrik, Zhiqiang Yu

Let $E = Rep (G)$ be a Tannakian fusion category. For a braided fusion category $C$ over $E$ we give sufficient and necessary conditions that char…

Realizing modular data from centers of near-group categories

Zhiqiang Yu, Qing Zhang

In this paper, we show the existence of a near-group category of type $Z /4 Z \times Z /4 Z + 16$ and compute the modular data of its Drinfeld cen…

On the center of near-group fusion category of type $Z_{3} + 6$

Zhiqiang Yu

Let $A$ be a near-group fusion category of type $Z_{3} + 6$ . We show that there is a modular tensor equivalence $\mathcal{Z}(\mathcal{A})\cong\mathcal{C}(\mathbb{Z}_…
