$Z_2^k$ -流形的自旋结构和谱

Spin structures and spectra of $Z_2^k$-manifolds

Roberto Miatello, Ricardo Podesta

摘要:

给出了具有和乐群$Z_2^k$的黎曼流形上存在pin+,pin-和spin结构的充要条件.对于任何n>3(分别为n>5)我们给出了紧流形对的例子(分别是紧可定向流形)M_1,M_2,彼此非同胚,它们在函数上和p-形式上都是Laplace等谱的,且使得M_1允许pin+或pin-,(分别为.自旋)结构,而M_2则没有。

英文摘要:

We give necessary and sufficient conditions for the existence of pin+, pin- and spin structures on Riemannian manifolds with holonomy group $Z_2^k$. For any n>3 (resp. n>5) we give examples of pairs of compact manifolds (resp. compact orientable manifolds) M_1, M_2, non homeomorphic to each other, that are Laplace isospectral on functions and on p-forms for any p and such that M_1 admits a pin+, or pin-, (resp. spin) structure whereas M_2 does not.
