A型模范畴的Verlinde公式的旋分解

A spin decomposition of the Verlinde formula for type A modular categories

Christian Blanchet

摘要:

模范畴是具有一些额外代数特征的辫范畴。这个概念的兴趣在于它提供了三维空间的拓扑量子场论。与模范畴相关的Verlinde公式是TQFT模的维数。我们计算了这些公式并讨论了与SU(N)有关的模范畴的约化和加细,主要结果是Verlinde公式的分裂,对应于TQFT模的砖形分解,其和项由模偶数的自旋结构来表示,我们引入了自旋模范畴的概念,并在一般的上下文中给出了分解定理的证明.

英文摘要:

A modular category is a braided category with some additional algebraic features. The interest of this concept is that it provides a Topological Quantum Field Theory in dimension 3. The Verlinde formulas associated with a modular category are the dimensions of the TQFT modules. We compute this formulas and discuss reductions and refinements for modular categories related with SU(N).Our main result is a splitting of the Verlinde formula, corresponding to a brick decomposition of the TQFT modules whose summands are indexed by spin structures modulo an even integer.We introduce the notion of a spin modular category, and give the proof of the decomposition theorem in this general context.
