Viewing finite dimensional representations through infinite dimensional ones

Dieter Happel, Birge Huisgen-Zimmermann

We develop criteria for deciding the contravariant finiteness status of a subcategory $A \subseteq Λ -mod$ , where $Λ$ is a finite dimensional algebra. In particular, given a…

Algebras of finite global dimension

Dieter Happel, Dan Zacharia

Let $Λ$ be a finite dimensional algebra over an algebraically closed field $k$ . We survey some results on algebras of finite global dimension and address some open problems.
