旗叶相关品种的K稳定性

K-stability of relative flag varieties

Anton Isopoussu

摘要:

我们推广的部分结果Yau-Tian-Donaldson对应的规则流形的丛的纤维是一个经典的旗品种。这是使用陈类计算涉及舒尔函子的组合。在黎曼曲面上工作时得到最强的结果。弱的部分结果得到绝热极化在任意尺寸的基础。我们发展了相对K-稳定性的概念,它将在基簇上工作的思想嵌入到K-稳定性理论中。滤过代数中的自然结构为测试配置的集合提供了额外的结构。我们用几个例子来说明这些结构。

英文摘要:

We generalise partial results about the Yau-Tian-Donaldson correspondence on ruled manifolds to bundles whose fibre is a classical flag variety. This is done using Chern class computations involving the combinatorics of Schur functors. The strongest results are obtained when working over a Riemann surface. Weaker partial results are obtained for adiabatic polarisations over a base of arbitrary dimension. We develop the notion of relative K-stability which embeds the idea of working over a base variety into the theory of K-stability. Natural constructions in filtered algebras equip the collection of test configuration with extra structures. We illustrate these constructions with several examples.
