Preprojective algebras of Dynkin type and two-sided tilting complexes
In this talk, we discuss tilting theory of preprojective algebras of Dynkin type. In the case of non-Dynkin type, we can give a simple and explicit description of two-sided tilting complexes, which provide auto-equivalences of the derived categories. On the other hand, in the case of Dynkin type, tilting theory is more involved and such a description hasn’t been discovered. In this talk, we discuss tilting theory of preprojective algebras of Dynkin type and explain a construction of two-sided tilting complexes.
