Title: Definable Categories

Abstract: Definable categories arose in the model theory of modules and have turned out to be a good context for additive model theory.  They are also algebraically natural and much theory and many applications have been developed.  The large context in which they sit ((anti-)equivalences of certain 2-categories, [2]) is paralleled in the non-additive/Set-based world and this has recently been shown, by Kuber and Rosicky [1], to run deeper than had previously seemed to be the case.
