报告题目:On perfect modualr categories
主讲人:董井成 教授(南京信息工程大学)
摘要:In this talk, we prove that modular categories of Frobenius-Perron dimension $p^2q^2r^2$ are solvable, where $p,q,r$ are distinct prime numbers. As applications, we get that integral modular categories of Frobenius-Perron dimension less than 1800 are solvable, and hence integral perfect modular categories have Frobenius-Perron dimension greater than or equal to 1800. When the modular categories considered are weakly group-theoretical, we further prove that integral perfect modular categories have Frobenius-Perron dimension greater than or equal to 3600.
