In this introductory review, we argue that a quantum structure of space-time naturally entails a higher-spin theory, to avoid significant Lorentz violation. A suitable framework is provided by Yang-Mills matrix models, which allow to consider space-time as a physical system, which is treated on the same footing as the fields that live on it. We discuss a specific quantum space-time solution, whose internal structure leads to a consistent and ghost-free higher-spin gauge theory. The spin 2 modes give rise to metric perturbations, which include the standard gravitons as well as the linearized Schwarzschild solution.

关于矩阵模型中时空、引力和高自旋的量子结构

在这篇介绍性评论中，我们认为时空的量子结构自然需要高自旋理论，以避免严重的洛伦兹违反。Yang-Mills 矩阵模型提供了一个合适的框架，它允许将时空视为一个物理系统，它与生活在其上的场处于相同的基础上。我们讨论了一个特定的量子时空解决方案，其内部结构导致了一致且无重影的高自旋规范理论。自旋 2 模式引起度量扰动，其中包括标准引力子以及线性化 Schwarzschild 解。
