    Title: On generalizations of an old theorem of Rickard's
      
      Abstract: In 1989 Rickard published a couple of papers on Morita
      equivalence of
      derived categories. We will begin with a quick review of his results.
      
      The interest in this old result was revived in 2018 by Krause, who
      asked for improvements. Krause's question almost immediately led
      to a couple of results we will briefly review.
      
      And then we will talk about very recent work, joint with Canonaco
      and Stellari, which goes much further in improving Rickard's
      theorem. This is work still in progress, in the sense that we are
      trying to sharpen and generalize the theorems that we can already
      prove.
