AI总结:

本文研究复流形上的非交换变形及SYZ变换,扩展了非交换线丛构造并探讨其镜像对偶对象。

摘要:

通过将给定的n维复流形X^n视为平凡流形纤维化X^n→R^n/Z^n,我们可以基于SYZ构造获得一个镜像对偶的复化辛流形检查X^n。2000年代中期,作为对X^n非交换变形研究的一部分,Kajiura研究了通过由定义在纤维上的泊松双矢量θ进行的(实)非形式变形量子化所获得的非交换复流形X_θ^n。特别是,他构建了X^n上解析线丛L_θ→X_θ^n的非交换变形以及由它们构成的曲dg-范畴。另一方面,与此非交换变形相关,我们可以通过用合适的同构 twisting 来构造一个非平凡的平凡解析线丛的变形。在本文中,从这一观点出发,我们将L_θ的构造扩展到更一般的设置。此外,我们还考虑定义在X_θ^n镜像伴侣上的对象,这些对象与扩展的非交换对象镜像对偶。

英文摘要:

By regarding a given $n$-dimensional complex torus $X^n$ as the trivial torus fibration $X^n \to \mathbb{R}^n/\mathbb{Z}^n$, we can obtain a mirror dual complexified symplectic torus $\check{X}^n$ based on the SYZ construction. In the middle 2000s, as a part of the study on noncommutative deformations of $X^n$, Kajiura examined the noncommutative complex torus $X_θ^n$ obtained via the (real) nonformal deformation quantization of $X^n \to \mathbb{R}^n/\mathbb{Z}^n$ by a Poisson bivector $θ$ defined along the fibers. In particular, he constructed the noncommutative deformations $L_θ \to X_θ^n$ of holomorphic line bundles on $X^n$ and a curved dg-category consisting of them. On the other hand, associated to this noncommutative deformation, we can construct a non-trivial deformation of the trivial holomorphic line bundle on $X^n$ by twisting it with a suitable isomorphism. In this paper, from this point of view, we extend the construction of $L_θ$ to the more general setting. Moreover, we also consider objects defined on a mirror partner of $X_θ^n$ which are mirror dual to such extended noncommutative objects.
