DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GDEq/55/">On
  the algebras of nonlocal symmetries for the (modified) 4D Martı́nez Alo
 nso-Shabat equation</a>\nby Petr Vojčák as part of Geometry of different
 ial equations seminar\n\n\nAbstract\nWe consider two four-dimensional Lax-
 integrable equations known as the 4D Martı́nez Alonso-Shabat equation an
 d the modified Martı́nez Alonso-Shabat equation\, respectively. We const
 ruct two differential coverings for both of them and describe the algebras
  of nonlocal symmetries in these coverings. We also analyze the actions of
  the known recursion operators on these nonlocal symmetries.\n\nPartially 
 based on a joint work with Joseph Krasil'shchik.\n
