覆盖、对应与非对易几何

Coverings, correspondences, and noncommutative geometry

Matilde Marcolli, Ahmad Zainy al-Yasry

摘要:

我们构建了一个添加剂的范畴,其中的对象是嵌入图中的3-球面和态射的几何对应3-流形实现以不同的方式作为分支覆盖的3-球面,分支覆盖配边。我们认为动力系统从相关的卷积代数赋予时间演化定义的基础几何。我们描述的相关性,我们的建设的问题,在非交换几何的谱对应。

英文摘要:

We construct an additive category where objects are embedded graphs in the 3-sphere and morphisms are geometric correspondences given by 3-manifolds realized in different ways as branched covers of the 3-sphere, up to branched cover cobordisms. We consider dynamical systems obtained from associated convolution algebras endowed with time evolutions defined in terms of the underlying geometries. We describe the relevance of our construction to the problem of spectral correspondences in noncommutative geometry.
