Julia Sauter (Bielefeld), Cotilting the generator correspondence.

Abstract:
The generator corresponce is a classical result of Kato and Tachikawa characterising endomorphism rings of generators. We understand this result through the theory of recollements and give a characterisation of a canonical cotilt of it. This is joint work in progress with Matthew Pressland.
