代数理论的$ω$-范畴化

The $ω$-categorification of Algebraic Theories

Phillip M Bressie

AI总结:

本文通过将Leinster的球状operad扩展为球状PRO并引入收缩结构,构造了一个monad,其代数为任意等式代数理论的弱$ω$-范畴化,其中初始弱化给出完全弱化的$ω$-范畴化。

摘要:

Batanin和Leinster关于球状operad的工作提供了弱$ω$-范畴众多潜在定义之一。通过球状operad的语言,他们构造了一个monad,其代数码码编码弱$ω$-范畴。本文的目的是展示如何构造一个类似的monad,使我们能够表述任意等式代数理论的弱$ω$-范畴化。我们首先回顾经典operad理论和PRO理论。然后我们展示如何通过对collection范畴的范畴富化,将Leinster的球状operad扩展为球状PRO理论。接着证明,一个称为球状化的过程允许我们从经典PRO P构造一个球状PRO,其代数是P的那些内在于严格$ω$-范畴和严格$ω$-函子范畴中的代数。随后,Leinster关于球状operad上收缩结构的概念被扩展到球状PRO的情境中,以构造一个monad,其代数是经典PRO P的球状化的弱化。在这些弱化中,存在一个初始弱化,其代数按构造即为P所编码的代数理论的完全弱化$ω$-范畴化。

英文摘要:

Batanin and Leinster's work on globular operads has provided one of many potential defnitions of a weak $ω$-category. Through the language of globular operads they construct a monad whose algebras encode weak $ω$-categories. The purpose of this work is to show how to construct a similar monad which will allow us to formulate weak $ω$-categorifications of any equational algebraic theory. We first review the classical theory of operads and PROs. We then present how Leinster's globular operads can be extended to a theory of globular PROs via categorical enrichment over the category of collections. It is then shown how a process called globularization allows us to construct from a classical PRO P a globular PRO whose algebras are those algebras for P which are internal to the category of strict $ω$-categories and strict $ω$-functors. Leinster's notion of a contraction structure on a globular operad is then extended to this setting of globular PROs in order to build a monad whose algebras are weakenings of the globularization of the classica PRO P. Among these weakenings is the initial weakining whose algebras are by construction the fully weakened $ω$-categorifications of the algebraic theory encoded by P.
