Query: Describing coherent sheaves on projective spaces via Koszul duality   A new section on projections of coherent sheaves from a projective space to a
lower-dimensional projective space has been added.
  Also some of the notation has been altered to bring it into line with the
joint paper with Eisenbud and Schreyer.
