费米6 $j$ -超聚变范畴中的符号
Fermionic 6$j$-symbols in superfusion categories
摘要:
我们描述了如何研究超融合范畴(粗略地说,融合范畴丰富的超向量空间的范畴)减少到融合范畴sVect,在这个意义上的德林费尔德,Gelaki,Nikshych,和Ostrik。在Brundan和Ellis的基础上,我们给出了超融合范畴的基础融合范畴的构造,并给出了超融合范畴中结合子的6个$j$ -符号的显式公式.给出了超融合范畴的$π$ -Grothendieck环的定义,证明了超融合范畴的Ocneanu刚性的一个形式.
英文摘要:
We describe how the study of superfusion categories (roughly speaking, fusion categories enriched over the category of super vector spaces) reduces to that of fusion categories over sVect, in the sense of Drinfeld, Gelaki, Nikshych, and Ostrik. Following Brundan and Ellis, we give the construction of the underlying fusion category of a superfusion category, and give an explicit formula for the associator in this category in terms of 6$j$-symbols. We give a definition of the $π$-Grothendieck ring of a superfusion category, and prove a version of Ocneanu rigidity for superfusion categories.
