摘要:

在弦/M理论的矩阵模型方法中,人们从一般对称性$gl(\infty)$出发来再现时空流形。在本文中,我们考虑的推广,其中的时空流形出现从规范对称性代数不一定是$gl(\infty)$。我们专注于第二个非平凡的例子后,环形紧化,陪集空间$G/H$,并提出了一个具体的无限维对称实现的几何。它由陪集上的规范代数值函数和与等距有关的洛伦兹生成元对组成。我们表明,$0$维规范理论的质量和陈-西蒙斯条款给出了规范理论的陪集与标量场与$H$。

英文摘要:

In the matrix model approaches of string/M theories, one starts from a generic symmetry $gl(\infty)$ to reproduce the space-time manifold. In this paper, we consider the generalization in which the space-time manifold emerges from a gauge symmetry algebra which is not necessarily $gl(\infty)$. We focus on the second nontrivial example after the toroidal compactification, the coset space $G/H$, and propose a specific infinite-dimensional symmetry which realizes the geometry. It consists of the gauge-algebra valued functions on the coset and Lorentzian generator pairs associated with the isometry. We show that the $0$-dimensional gauge theory with the mass and Chern-Simons terms gives the gauge theory on the coset with scalar fields associated with $H$.
