终周期算子的一个指标定理

An index theorem for end-periodic operators

Tomasz Mrowka, Daniel Ruberman, Nikolai Saveliev

摘要:

我们将一阶微分算子的Atiyah、Patodi和Singer指标定理从具有圆柱端点的流形推广到具有周期端点的流形。这个定理是对Taubes的Fredholm理论的一个自然的补充。我们的指数定理表示在一个新的周期η-不变,等于阿蒂亚-帕托迪-辛格η-不变的圆柱设置。我们应用这个周期η-不变量来研究正数量曲率的黎曼度量的模空间。

英文摘要:

We extend the Atiyah, Patodi, and Singer index theorem for first order differential operators from the context of manifolds with cylindrical ends to manifolds with periodic ends. This theorem provides a natural complement to Taubes' Fredholm theory for general end-periodic operators. Our index theorem is expressed in terms of a new periodic eta-invariant that equals the Atiyah-Patodi-Singer eta-invariant in the cylindrical setting. We apply this periodic eta-invariant to the study of moduli spaces of Riemannian metrics of positive scalar curvature.
