However\, in the last few years w e have seen indications that a similar statement can be made about stable module categories. Those are categories whose objects are the usual module s\, but morphisms are formed by modding out maps factoring through project ives (or injectives). Additive functors defined on such categories are als o said to be stable\, and the study of such functors adds even more insigh ts. The goal of this talk is to illustrate this thesis with simple example s. We shall see how several familiar classes of rings can be characterized by properties of their stable functors. This will be an expository talk. No prior knowledge of functor categories is assumed or needed.\n LOCATION:https://researchseminars.org/talk/ONCAS/3/ END:VEVENT END:VCALENDAR
