非对易几何中的谱Action

Spectral Action in Noncommutative Geometry

Michał Eckstein, Bruno Iochum

摘要:

什么是光谱作用量,如何计算它,已知的例子有哪些?这本书提供了一个导游通过数学栖息地的noncommutative几何à拉康纳斯,故意揭开这些问题的答案。在简要介绍谱方法的基础上,给出了谱三元组的简明入门。第2章的目的是作为一个工具包的计算。第三章深入探讨了热算子迹的渐近展开式与相关谱Zeta函数的亚纯延拓之间的微妙联系。第四章研究了规范势涨落下的谱作用量的行为。第五章列出了该领域的一系列悬而未决的问题。这本书的结论是一个附录,包括一些辅助工具,从几何和分析,以及光谱几何的例子。这本书既作为一个纲要的研究人员在领域的非交换几何和邀请数学物理学家寻找新的概念。

英文摘要:

What is spectral action, how to compute it and what are the known examples? This book offers a guided tour through the mathematical habitat of noncommutative geometry à la Connes, deliberately unveiling the answers to these questions. After a brief preface flashing the panorama of the spectral approach, a concise primer on spectral triples is given. Chapter 2 is designed to serve as a toolkit for computations. The third chapter offers an in-depth view into the subtle links between the asymptotic expansions of traces of heat operators and meromorphic extensions of the associated spectral zeta functions. Chapter 4 studies the behaviour of the spectral action under fluctuations by gauge potentials. A subjective list of open problems in the field is spelled out in the fifth Chapter. The book concludes with an appendix including some auxiliary tools from geometry and analysis, along with examples of spectral geometries. The book serves both as a compendium for researchers in the domain of noncommutative geometry and an invitation to mathematical physicists looking for new concepts.
