DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GDEq/81/">On
  invariants and equivalence differential operators under algebraic Lie pse
 udogroups actions</a>\nby Valentin Lychagin as part of Geometry of differe
 ntial equations seminar\n\nLecture held in room 303 of the Independent Uni
 versity of Moscow.\n\nAbstract\nIt is the concluding talk on invariants an
 d the equivalence of differential operators under actions of Lie pseudogro
 ups. We'll show\, that under some natural algebraic restrictions on Lie ps
 eudogroups and nonlinearities of differential operators under consideratio
 n\, there is a reasonable description of their orbits under the Lie pseudo
 groups\, as well as local model forms. Then\, the general approach will be
  applied to the Cartan list of primitive Lie pseudogroups.\n
