手征代数上的模

Modules Over a Chiral Algebra

N. Rozenblyum

摘要:

给定一个手征代数,研究曲线的任意幂上的模。我们用三种不同的方法来描述这个范畴:因子分解,手征运算和作为某个张量范畴中的李代数的模。此外,我们考虑类似的问题,李-* 代数和分解空间。对于因子分解空间,我们给出了一个建设的multijets在一定的Weil限制,让我们的特点counital可因子分解的代数堆栈作为multijets。

英文摘要:

Given a chiral algebra, we study modules over an arbitrary power of a curve. We describe this category in three different ways: in terms of factorization, in terms of certain chiral operations and as modules for a lie algebra in a certain tensor category. In addition, we consider analogous questions for LIe-* algebras and factorization spaces. For factorization spaces, we give a construction of multijets in terms of a certain Weil restriction which lets us characterize counital factorizable algebraic stacks as multijets.
