Abstract
- We explore some properties of wide subcategories of the category mod$\,(��)$ of finitely generated left $��$-modules, for some artin algebra $��.$ 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 $\mathcal{X}$ in mod$\,(��),$ we give necessary and sufficient conditions to see that $\mathcal{X}=\mathrm{pres}\,(P),$ for some projective $��$-module $P;$ and finally, a connection with ring epimorphisms is given.<br />14 pages, 2 figures
