We prove that topological Hochschild homology (THH) arises from a presheaf of circles on a certain combinatorial category, which gives a universal construction of THH for any enriched infinity category. Our results rely crucially on an elementary, model-independent framework for enriched higher category theory, which may be of independent interest.

THH 和丰富类别的痕迹

我们证明拓扑霍克希尔德同调（THH）源自某个组合范畴上的一组预层圆，这为任何丰富的无穷大范畴给出了 THH 的普遍构造。我们的结果主要依赖于一个基本的、独立于模型的框架，用于丰富的高级范畴理论，这可能是独立的兴趣。
