高维范畴论中的结构

Structures in higher-dimensional category theory

Tom Leinster

摘要:

这篇论文写于1998年,主要通过广义操作和多范畴理论来阐明各种高级范畴结构。第一章和第二章讨论了这个理论及其在弱n-范畴定义中的应用,这两章在很大程度上被我的论文(math.CT/0011106)所取代,但第三章和第四章没有在其他地方出现。第三章的主要结果是小灰范畴可以被刻画为2-范畴、同态、强变换和修改的三范畴的子三范畴;在更高的维度上也有一个关于相干性的猜想。第四章定义了opetopes和一个对于每个n的n-粘贴图的范畴,在n=2的情况下,它是树的范畴的定义。

英文摘要:

This paper, written in 1998, aims to clarify various higher categorical structures, mostly through the theory of generalized operads and multicategories. Chapters I and II, which cover this theory and its application to give a definition of weak n-category, are largely superseded by my thesis (math.CT/0011106), but Chapters III and IV have not appeared elsewhere. The main result of Chapter III is that small Gray-categories can be characterized as the sub-tricategories of the tricategory of 2-categories, homomorphisms, strong transformations and modifications; there is also a conjecture on coherence in higher dimensions. Chapter IV defines opetopes and a category of n-pasting diagrams for each n, which in the case n=2 is a definition of the category of trees.
