Let Wn(K) be the Lie algebra of derivations of the polynomial algebra K[X] := K[x1, . . . , xn] over an algebraically closed field K of characteristic zero. A subalgebra L ⊆ Wn(K) is called polynomial if it is a submodule of the K[X]-module Wn(K). We prove that the centralizer of every nonzero ele...
