Jorge Vitoria and Frederik Marks, Localisations of rings in representation
theory I and II.
Ring epimorphisms are important tools to describe certain
subcategories of the module category of a ring. In these talks we will
use localisation techniques to characterise some classes of ring
The first talk will focus on torsion-theoretical localisations, after
Gabriel, and their relation with flat ring epimorphisms.
In the second talk we will discuss universal localisations, after Cohn
and Schofield, and a generalised version due to Krause. These
localisations will be useful to describe certain homological ring
