Abstract:
The main result of this paper asserts that it suffices to prove the Jacobian Conjecture for all polynomial maps of the form , where is homogeneous (of degree 3) and is nilpotent and symmetric. Also a 6-dimensional counterexample is given to a dependence problem posed by de Bondt and van den Essen (2003).
