AI总结:

本文提出了一种基于非有限张量范畴的映射群表示,展示了其与三维全息原理的关联,并证明了其在共形块研究中的延续性。

摘要:

我们证明,一个具有足够紧致投射对象的紧致刚平衡编织单向范畴能够产生一种与沿标记区间粘合兼容的模映射群表示。考虑非有限张量范畴的动机在于顶点算子代数理论,其中此类范畴出现为模范畴。本文提出的映射群表示具有因子同调描述。换句话说,它们具有三维起源,因此遵循全息原理。一个紧致投射对称弗罗贝尼乌斯代数使这些表示具有一个映射群不变的指向,并且与沿区间粘合兼容。这表明,至少在某种程度上,许多用于构造和研究共形块和相关子的工具仍可在非有限但刚性的设定中使用。

英文摘要:

We show that a compact rigid balanced braided monoidal category with enough compact projective objects gives rise to a system of mapping class group representations compatible with the gluing along marked intervals. A motivation to consider non-finite tensor categories is the theory of vertex operator algebras where such categories arise as categories of modules. The mapping class group representations presented in this article admit a factorization homology description. In other words, they are of three-dimensional origin and hence obey a holographic principle. A compact projective symmetric Frobenius algebra endows the representations with a pointing that is mapping class group invariant and compatible with the gluing along intervals. This shows that, at least to some extent, many of the tools for the construction and study of spaces of conformal blocks and correlators remain available in a non-finite, but rigid setting.
