环面Landau-Ginzburg模型的突变等价性

Mutation equivalence of toric Landau-Ginzburg models

Thomas Prince

摘要:

给定Fano复曲面流形$Y$上由线丛$L_1,\ldots, L_c$的集合的截面定义的Fano完全交,Givental/Hori-Vafa构造了一个镜像对偶Landau-Ginzburg模型.该构造取决于选择合适的nef分区;即,由$Y$确定的扇形的射线的分区。我们表明,复曲面的Landau-Ginzburg模型从不同的NEF分区表示相同的完整的交叉相关的体积保持双有理映射。特别地,可以从这些Landau-Ginzburg模型获得的各种Laurent多项式镜像是突变等价的。

英文摘要:

Given a Fano complete intersection defined by sections of a collection nef line bundles $L_1,\ldots, L_c$ on a Fano toric manifold $Y$, a construction of Givental/Hori-Vafa provides a mirror-dual Landau-Ginzburg model. This construction depends on a choice of suitable nef partition; that is, a partition of the rays of the fan determined by $Y$. We show that toric Landau-Ginzburg models constructed from different nef partitions representing the same complete intersection are related by a volume preserving birational map. In particular, various Laurent polynomial mirrors which may be obtained from these Landau-Ginzburg models are mutation equivalent.
