Definable categories
Mike Prest (University of Manchester)
Abstract: A definable subcategory of a module category is one which is closed under direct products, directed colimits and pure submodules. Many interesting categories of this kind arise in homological algebra and representation theory. Definable categories have a rich internal structure and the natural functors between them mirror exact functors between associated small abelian categories. I will give a variety of examples and describe some of their features.
