Query: Generalized Amitsur-Levitski theorem and equations for sheets in a
  reductive complex Lie algebra   I connect an old result of mine on a Lie algebra generalization of the
Amitsur-Levitski theorem with equations for sheets in a reductive Lie algebra
and with recent results of Kostant-Wallach on the variety of singular elements
in a reductive Lie algebra.
