分布、叶理和G-流形上的transmitted狄拉克算子:讲义

Transversal Dirac operators on distributions, foliations, and G-manifolds: Lecture notes

Ken Richardson

摘要:

在这些概述讲座中,我们调查的几何和分析性质的横向狄拉克运营商。特别是,我们定义了一个横向狄拉克算子的分布,基本上是自伴(Prokhorenkov-R结果)。我们描述了Habib-R定理,证明了基本Dirac算子的谱在黎曼叶理上的不变性。Bruening-Kamber-R定理给出了G-流形上横截椭圆算子的等变指数和黎曼叶上基本Dirac算子的指数的Atiyah-Singer型公式。这些笔记在每个小节的末尾都包含练习,旨在供研究生使用。

英文摘要:

In these survey lectures, we investigate the geometric and analytic properties of transverse Dirac operators. In particular, we define a transverse Dirac operator associated to a distribution that is essentially self-adjoint (Prokhorenkov-R result). We describe the Habib-R Theorem showing that the invariance of the spectrum of a basic Dirac operator on a Riemannian foliation. The Bruening-Kamber-R theorems give Atiyah-Singer type formulas for the equivariant index of transversally elliptic operators on G-manifolds and the index of basic Dirac operators on Riemannian foliations. These notes contain exercises at the end of each subsection and are meant to be accessible to graduate students.
