DESCRIPTION:Title: <a href="https://researchseminars.org/talk/notts_ag/73/
 ">Hodge number are not derived invariants in positive characteristic</a>\n
 by Nicolas Addington (Oregon) as part of Online Nottingham algebraic geome
 try seminar\n\n\nAbstract\nDerived categories of coherent sheaves behave a
  lot like cohomology\, so it's natural to ask which cohomological invarian
 ts are preserved by derived equivalences. After discussing the motivation 
 and previous results\, I'll present a derived equivalence between Calabi-Y
 au 3-folds in characteristic 3 with different Hodge numbers\; this couldn'
 t happen in characteristic 0. The project has a substantial computer algeb
 ra component which I'll spend some time on.\n
