Bilinear forms on Green rings of finite dimensional Hopf algebras
Z. Wang, L. Li, Y. Zhang
In this paper, we study the Green ring and the stable Green ring of a Hopf algebra by means of bilinear forms. We show that the Green ring of a Hopf algebra of finite represent…

Integral almost square-free modular categories
Jingcheng Dong, Libin Li, Li Dai
We study integral almost square-free modular categories; i.e., integral modular categories of Frobenius-Perron dimension , where is a prime number, is a square-free n…
