Resumo

We explore some properties of wide subcategories of the category mod(A) of finitely generated left A-modules, for some artin algebra A. In particular we look at wide finitely generated subcategories and give a connection with the class of standard modules and standardly stratified algebras. Furthermore, for a wide class chi in mod(A), we give necessary and sufficient conditions to see that chi = pres(P), for some projective A-module P; and finally, a connection with ring epimorphisms is given.
