Several constructions for factorization systems
Theory and applications of categories, Tome 12 (2004), pp. 326-354
The paper develops the previously proposed approach to constructing factorization systems in general categories. This approach is applied to the problem of finding conditions under which a functor (not necessarily admitting a right adjoint) `reflects' factorization systems. In particular, a generalization of the well-known Cassidy-Héebert-Kelly factorization theorem is given. The problem of relating a factorization system to a pointed endofunctor is considered. Some relevant examples in concrete categories are given.
