Title: Homological algebra and artinian categories
Abstract:
We'll introduce the length of an object in an abelian category and review basic notions of homological algebra, like projective objects, exact sequences, and the Ext functors. Objects for which the length is finite are particularly well-behaved, so we'll study situations where this happens.
