Calabi-Yau代数

Calabi-Yau algebras

Victor Ginzburg

摘要:

我们介绍了一些新的代数结构自然产生的几何卡拉比-丘流形和镜像对称。利用非交换辛DG代数的分解给出了Calabi-Yau代数的一个泛构式。在3维中,分辨率由非对易势决定。卡-丘代数的表示簇与临界点的集合和势的消失圈层密切相关。数值不变量,如循环同调组的秩,预计将由“矩阵积分"表示品种。我们讨论了Calabi-Yau代数的例子,涉及箭图,三维McKay对应,crepant决议,Sklyanin代数,双曲3-流形和Chern-Simons。与量子Del Pezzo表面相关的例子将在[EtGi]中讨论。

英文摘要:

We introduce some new algebraic structures arising naturally in the geometry of Calabi-Yau manifolds and mirror symmetry. We give a universal construction of Calabi-Yau algebras in terms of a noncommutative symplectic DG algebra resolution. In dimension 3, the resolution is determined by a noncommutative potential. Representation varieties of the Calabi-Yau algebra are intimately related to the set of critical points, and to the sheaf of vanishing cycles of the potential. Numerical invariants, like ranks of cyclic homology groups, are expected to be given by `matrix integrals' over representation varieties. We discuss examples of Calabi-Yau algebras involving quivers, 3-dimensional McKay correspondence, crepant resolutions, Sklyanin algebras, hyperbolic 3-manifolds and Chern-Simons. Examples related to quantum Del Pezzo surfaces will be discussed in [EtGi].
