  • Theorem on the cohomology of the Grassmann-graded variational bicomplex on graded bundles
  • Solution of the global inverse problem of the calculus of variations in a very general setting
  • Global variational formula
  • First Noether theorem in a general setting of Grassmann-graded Lagrangians and their generalized  supersymmetries
