DESCRIPTION:Title: <a href="https://researchseminars.org/talk/mmandim/67/"
 >Symmetries and conservation laws for differential equations\, difference 
 equations and second-order delay ODEs</a>\nby Vladimir Dorodnitsyn (Keldys
 h Institute of Applied Mathematics\, Moscow\, Russia) as part of Mathemati
 cal models and integration methods\n\n\nAbstract\nThe report is devoted to
  operators identities for Lagrangian and the Hamiltonian\napproach to the 
 connection of symmetries of equations with conservation laws\, and the Lag
 randian\nidentity for equations which have no variational statement. We co
 nsider also difference equations and\nODEs with retarded argument and appr
 opriate operators identities.\n\nThis is based on joint works with Roman K
 ozlov\, Pavel Winternitz\, Sergey Meleshko and Evgenii Kaptsov.\n
