Cotilting sheaves over noncommutative curves

In this talk I will report on joint work with Rosanna Laking. We work in the category of quasicoherent sheaves over a weighted noncommutative regular projective curve, which is a certain type of a hereditary locally noetherian Grothendieck category without projectives. I will explain how the classification of non-coherent cotilting sheaves over a domestic, tubular or elliptic curve is done.
