Abstract

The immediate purpose of this paper is to show how Li's characterization of Green's relations on monoids of strong endomorphisms of graphs [8] is related to earlier work of Klasa [5] on categories. Li's results are thus extended to some categories of strong graph homomorphisms with more than one object, and a finiteness requirement is weakened. A further purpose is to extend Klasa's results in such a way as to better reflect the factorization properties of interesting concrete categories.
