Query: Elementary invariants for centralizers of nilpotent matrices   We construct an explicit set of algebraically independent generators for the
center of the universal enveloping algebra of the centralizer of a nilpotent
matrix in the Lie algebra gl_N(C). In particular, this gives a new proof of the
freeness of the center, a result first proved by Panyushev, Premet and Yakimova
(math.RT/0610049).
