DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GDEq/3/">Inv
 ariants of forth order linear differential operators</a>\nby Valery Yumagu
 zhin as part of Geometry of differential equations seminar\n\n\nAbstract\n
 The report is devoted to linear scalar differential operators of the fourt
 h order on 2-dimensional manifolds. The field of rational differential inv
 ariants of such operators will be described and their application to the e
 quivalence problem with respect to the group of diffeomorphisms of the man
 ifold will be shown.\n\nAlthough the talk will be in Russian\, the slides 
 will be in English and the discussion will be in both languages.\n
