三维空间中的量子引力和非对易时空:统一方法

Quantum gravity and non-commutative spacetimes in three dimensions: a unified approach

Bernd J Schroers

摘要:

这些笔记总结了陈-西蒙斯公式中三维引力的组合或哈密顿量子化的谈话,重点是量子群的作用和各种物理常数(c,G,Λ,\hbar)作为变形参数进入的方式。经典的情况进行了总结,其中的解决方案可以在模型时空(取决于c和Λ),连同全球标识通过相应的等距群的元素的特点。量子理论可以被看作是这幅图景的变形,用量子群代替了定域等距群,用非对易时空代替了经典模型时空。解释了这一观点,并概述了悬而未决的问题。

英文摘要:

These notes summarise a talk surveying the combinatorial or Hamiltonian quantisation of three dimensional gravity in the Chern-Simons formulation, with an emphasis on the role of quantum groups and on the way the various physical constants (c,G,Λ,\hbar) enter as deformation parameters. The classical situation is summarised, where solutions can be characterised in terms of model spacetimes (which depend on c and Λ), together with global identifications via elements of the corresponding isometry groups. The quantum theory may be viewed as a deformation of this picture, with quantum groups replacing the local isometry groups, and non-commutative spacetimes replacing the classical model spacetimes. This point of view is explained, and open issues are sketched.
