Lawvere理论

Notions of Lawvere theory

Stephen Lack, Jiri Rosicky

摘要:

范畴泛代数可以用Lawvere理论(单序有限积理论)或单子来构造,并且Lawvere理论范畴等价于集合上的有限单子范畴.我们展示了这种等价性,以及泛代数的基本结果,可以用三种方式来推广:用另一种类别替换集合,在丰富的环境中工作,以及用另一类极限而不是有限乘积工作。一个重要的特殊情况涉及到使用筛选的colimit保持单子,而不是过滤的colimit保持单子。

英文摘要:

Categorical universal algebra can be developed either using Lawvere theories (single-sorted finite product theories) or using monads, and the category of Lawvere theories is equivalent to the category of finitary monads on Set. We show how this equivalence, and the basic results of universal algebra, can be generalized in three ways: replacing Set by another category, working in an enriched setting, and by working with another class of limits than finite products. An important special case involves working with sifted-colimit-preserving monads rather than filtered-colimit-preserving ones.
