From ring epimorphisms to universal localisations

Frederik Marks / Jorge Vitória
Published Online: 2013-03-21 | DOI: https://doi.org/10.1515/forum-2012-0103


For a fixed ring, different classes of ring epimorphisms and localisation maps are compared. In fact, we provide sufficient conditions for a ring epimorphism to be a universal localisation. Furthermore, we consider recollements induced by some homological ring epimorphisms and investigate whether they yield recollements of derived module categories.

Keywords: Ring epimorphism; perfect localisation; universal localisation; recollement
