抛物型Hitchin系统的Springer对应与镜像对称

Springer correspondence and mirror symmetries for parabolic Hitchin systems

Bin Wang, Xueqing Wen, Yaoxiong Wen

AI总结:

本文通过构造幂零轨道闭包相关的一般Hitchin纤维并分析其与抛物型Hitchin系统一般纤维的关系,证明了B、C型抛物型Hitchin系统的SYZ与拓扑镜像对称,并给出Springer对偶和Lusztig典范商的新几何解释。

摘要:

我们证明了B型和C型抛物型Hitchin系统的Strominger--Yau--Zaslow镜像对称和拓扑镜像对称。与A型情形不同,这里必须对Springer对偶给出一种几何重新解释。此外,与非抛物型情形中Hitchin的构造不同,由于Springer对偶幂零轨道划分的改变,B型和C型中一般纤维之间的映射需要更多分析,这是本文的主要困难。为应对这一挑战,我们首先构造并研究关联于幂零轨道闭包的Higgs丛模空间的一般Hitchin纤维的几何。然后我们研究它们与抛物型Hitchin系统的一般Hitchin纤维之间的关系。沿着这一路径,我们建立了Springer对偶、Kazhdan--Lusztig映射与谱曲线奇点之间的有趣联系,并揭示了Lusztig典范商的一个新的几何解释。

英文摘要:

We prove the Strominger--Yau--Zaslow and topological mirror symmetries for parabolic Hitchin systems of types B and C. In contrast to type A, a geometric reinterpretation of Springer duality is necessary. Furthermore, unlike Hitchin's construction in the non-parabolic case, the map between generic fibers in type B and C needs more analysis due to the change of partitions of Springer dual nilpotent orbits, which is the main difficulty in this article. To tackle this challenge, we first construct and study the geometry of the generic Hitchin fibers of moduli spaces of Higgs bundles associated to the nilpotent orbit closures. Then we study their relation with the generic Hitchin fibers of parabolic Hitchin systems. Along this way, we establish intriguing connections between Springer duality, Kazhdan--Lusztig maps, and singularities of spectral curves, and uncover a new geometric interpretation of Lusztig's canonical quotient.
