简单弦图和n倍半范畴

Simple string diagrams and n-sesquicategories

Manuel Araújo

摘要:

我们定义了一个单子$T_n^{\operatorname{D^s}}$的操作是由简单的字符串图编码,我们定义$n$ -sesquicategories代数在这个单子。这个单子编码了$n$维弦图的组成结构。我们给出了生成元和关系描述的$T_n^{\operatorname{D^s}}$,这使我们能够描述$n$ -sesquicategories作为$n$ -球集配备了联合和单位的合成和whiskering操作。人们也可以把它们看作严格的$n$ --没有交换法则的范畴。最后给出了$n$ -半范畴的一个归纳刻画.

英文摘要:

We define a monad $T_n^{\operatorname{D^s}}$ whose operations are encoded by simple string diagrams and we define $n$-sesquicategories as algebras over this monad. This monad encodes the compositional structure of $n$-dimensional string diagrams. We give a generators and relations description of $T_n^{\operatorname{D^s}}$ , which allows us to describe $n$-sesquicategories as $n$-globular sets equipped with associative and unital composition and whiskering operations. One can also see them as strict $n$-categories without interchange laws. Finally we give an inductive characterization of $n$-sesquicategories.
