"Fully faithful embeddings between derived categories of algebras"

Abstract:
We will present necessary and sufficient conditions on a bimodule for the derived versions of the Hom functor and the tensor product to give fully faithful embeddings between the respective derived categories. We will show that the bimodules satisfying these conditions are closely connected to the infinite dimensional tilting modules, with a special role played by the so-called good tilting modules, as introduced by Bazzoni-Mantese-Tonolo. We will show that, however, both theories are not equivalent and we will present counterexamples.

"Large tilting modules and sheaves for canonical algebras"

Abstract:
We give a complete classification of large quasi-coherent tilting sheaves over an exceptional curve X (= generalisation of a weighted projective line) in case X is domestic or tubular. As application we get a classification of large tilting modules over a (concealed-) canonical algebra of domestic or tubular type. This is joint work with Lidia Angeleri.
