A Non-Abelian, Categorical Ontology of Spacetimes and Quantum Gravity

非阿贝尔代数拓扑

非阿贝尔代数拓扑是代数拓扑的一个分支，主要研究不可交换的高维代数.

拓扑序

在物理学中，拓扑序 是在零温物质（也称量子物质）相中的一种序. 宏观上，拓扑序是由稳固的基态简并 和简并基态的量子化非阿贝尔几何相所定义和描述的. 在微观上，拓扑序对应长程量子纠缠的.

Nonabelia algebraic topology

In mathematics, nonabelian algebraic topology studies an aspect of algebraic topology that involves (inevitably noncommutative) higher-dimensional algebras.

Topological order

In physics, topological order is a kind of order in zero-temperature phase of matter (also known as quantum matter).
