有限体积双曲流形上的Dirac算子

The Dirac Operator on Hyperbolic Manifolds of Finite Volume

Christian Baer

摘要:

研究有限体积双曲流形上狄拉克算子的谱。根据自旋结构,它要么是离散的,要么是整个实数线。对于S^3中的链补,我们用环绕数给出了一个简单的判据,判断何时出现本质谱。本文计算了退化为有限体积非紧双曲流形的闭双曲2-流形或闭双曲3-流形序列的特征值的积累率。事实证明,在三维空间中根本没有聚类。

英文摘要:

We study the spectrum of the Dirac operator on hyperbolic manifolds of finite volume. Depending on the spin structure it is either discrete or the whole real line. For link complements in S^3 we give a simple criterion in terms of linking numbers for when essential spectrum can occur. We compute the accumulation rate of the eigenvalues of a sequence of closed hyperbolic 2- or 3-manifolds degenerating into a noncompact hyperbolic manifold of finite volume. It turns out that in three dimensions there is no clustering at all.
