erratum: pdf
on locally presentable and accessible categories. There is an erratum made available by the authors:
accessible categories: see also sketch
algebraic categories: see algebraic category, equationally presentable category, essentially algebraic theory, and variety of algebras
injectivity class?es: see also weak factorization system
categories of models: see internal logic, theory, essentially algebraic theory, model
Locally presentable categories: Cocomplete possibly-large categories generated under filtered colimits by small generators under small relations. Equivalently, accessible reflective localizations of free cocompletions. Accessible categories omit the cocompleteness requirement; toposes add the requirement of a left exact localization.
