与谱三元组相关的Callias型算子

Callias-type operators associated to spectral triples

Hermann Schulz-Baldes, Tom Stoiber

摘要:

Callias型(或Dirac-Schrödinger)与抽象的半有限谱三元组的运营商的介绍和他们的指数计算的相关指数配对来自谱三元组。结果,然后解释为一个指标定理的非交换模拟的频谱流。偶数和奇数谱三元组被认为是,交换和非交换的例子。

英文摘要:

Callias-type (or Dirac-Schrödinger) operators associated to abstract semifinite spectral triples are introduced and their indices are computed in terms of an associated index pairing derived from the spectral triple. The result is then interpreted as an index theorem for a non-commutative analogue of spectral flow. Both even and odd spectral triples are considered, and both commutative and non-commutative examples are given.
