Explicit Happel-Reiten-Smalo tilting


Giovedi 5 giugno alle 17:00 in aula 2AB/40 Behrang Noohi (Florida State University) terra' un seminario dal titolo "Explicit Happel-Reiten-Smalo tilting".

I give an alternative, and very explicit, description of the abelian category B associated to a torsion pair (T,F) in an abelian category A. I then use this to give an explicit description of the category Ch(B) of chain complexes in B, the derived category D(B), and the DG structure on Ch(B) in terms of decorated complexes.
