2 Remark 1. 1) is an isomorphism. 1)). 2. 1) is an isomorphism for every finite discrete category J iff δ is an isomorphism when J is the empty set and when J is the two-element set. The latter means that for every pair D, D : D → Set 21 22 Chapter 2 of diagrams, the colimit of the diagram D × D : D × D → Set, (d, d ) → Dd × D d is canonically isomorphic to colim D × colim D . 3 Example 1. Colimits of ω-chains are filtered. Here the category D is the partially ordered set, or poset, of natural numbers, considered as a category.

This shows that algebraic categories can be characterized by their universal property: they are precisely the free sifted-colimit completions of small categories with finite coproducts. 12). 3), all we need to establish is the existence of finite coproducts. Indeed, coproducts then exist because they are filtered colimits of finite coproducts. 7). 13: finite coproducts of representable algebras, including an initial object, exist in Alg T . 14. 2 Lemma Given an algebraic theory T , for every functor A in Set T , the following conditions are equivalent: 1.

We denote by Alg T the category of algebras of T . Morphisms, called homomorphisms, are the natural transformations; that is, Alg T is a full subcategory of the functor category Set T . 2 Definition A category is algebraic if it is equivalent to Alg T for some algebraic theory T . 3 Remark An algebraic theory is by definition a small category. However, throughout the book, we do not take care of the difference between small and essentially small: a category is essentially small if it is equivalent to a small category.
