自旋模范畴

Spin Modular Categories

Anna Beliakova, Christian Blanchet, Eva Contreras

摘要:

模范畴是量子3流形不变量的一个著名来源。在本文中,我们研究结构的模范畴,允许定义的量子3流形不变量的细化涉及上同调类或广义自旋和复杂的自旋结构。在我们的构造中,在张量积下可逆的对象起着至关重要的作用。Witten-Reshetikhin-Turaev 3-流形不变量的上同调或自旋型加细的所有已知例子都是我们构造的特例。此外,我们建立了一个分裂公式的细化不变量,推广到著名的量子不变量的投影和那些由连接矩阵的乘积分解。

英文摘要:

Modular categories are a well-known source of quantum 3-manifold invariants. In this paper we study structures on modular categories which allow to define refinements of quantum 3-manifold invariants involving cohomology classes or generalized spin and complex spin structures. A crucial role in our construction is played by objects which are invertible under tensor product. All known examples of cohomological or spin type refinements of the Witten-Reshetikhin-Turaev 3-manifold invariants are special cases of our construction. In addition, we establish a splitting formula for the refined invariants, generalizing the well-known product decomposition of quantum invariants into projective ones and those determined by the linking matrix.
