U-Projectors and Fields of U-Invariants

  • K. A. Vyatkina
  • A. N. Panov


We present a general construction of the U-projector (the homomorphism of an algebra into its field of U-invariants identical on the subalgebra of U-invariants). It is shown how to apply the U-projector to find the systems of free generators of the fields of U-invariants for representations of reductive groups.
