The Hole Argument in Homotopy Type Theory

The Hole Argument is primarily about the meaning of general covariance in general relativity. As such it raises many deep issues about identity in mathematics and physics, the ontology of space–time, and how scientific representation works. This paper is about the application of a new foundational programme in mathematics, namely homotopy type theory (HoTT), to the Hole Argument. It is argued that the framework of HoTT provides a natural resolution of the Hole Argument. The role of the Univalence Axiom in the treatment of the Hole Argument in HoTT is clarified.

同伦类型论中的空洞论证

Hole 论证主要是关于广义相对论中广义协方差的含义。因此,它提出了许多关于数学和物理学中的同一性、时空本体论以及科学表示如何运作的深刻问题。这篇论文是关于数学中一个新的基础程序,即同伦类型理论 (HoTT),在 Hole Argument 中的应用。有人认为,HoTT 的框架提供了 Hole Argument 的自然解决方案。阐明了单价公理在处理 HoTT 中的 Hole Argument 中的作用。
