Serie di tre lezioni: 28/2 (Aula L), 6/3 (Aula G), 13/3/2012 (Aula G), inizio ore 14:00 Ring-theoretical localisation is a set of techniques used to invert elements in a ring. In these lectures we will study these techniques, starting with commutative rings and with their geometric counterparts, and we will aim to develop some geometric intuition for localisation ideas in noncommutative algebra. An essential tool for this will be the use of torsion-theoretical ideas in the category of modules, to which a geometric flavour is, therefore, assigned.
