连贯性

The Syntax of Coherence

Noson S. Yanofsky

摘要:

本文处理的范畴连贯性内的二维推广Lawvere的函语义。2-理论是一种用结构描述范畴的句法方法。从这里提供的角度来看,许多相干结果成为简单的陈述准Yoneda引理和2理论态射。给定两个2-理论和它们之间的一个2-理论-态射,研究了相应的2-代数范畴之间的诱导关系。导出拟伴随的强度由2-理论态射的强度分类。这些拟伴随反映了一个结构可以被另一个结构取代的程度。一个二维类似的克罗内克产品的定义和构造。这种操作允许人们从旧的一致性定律中产生新的一致性定律。

英文摘要:

This article tackles categorical coherence within a two-dimensional generalization of Lawvere's functorial semantics. 2-theories, a syntactical way of describing categories with structure, are presented. From the perspective here afforded, many coherence results become simple statements about the quasi-Yoneda lemma and 2-theory-morphisms. Given two 2-theories and a 2-theory-morphism between them, we explore the induced relationship between the corresponding 2-categories of algebras. The strength of the induced quasi-adjoints are classified by the strength of the 2-theory-morphism. These quasi-adjoints reflect the extent to which one structure can be replaced by another. A two-dimensional analogue of the Kronecker product is defined and constructed. This operation allows one to generate new coherence laws from old ones.
