Original Kurzfassung:
For a polynomial map f:k^n?k^m (k a field), we investigate those polynomials g?k[t1,?,tn] that can be written as a composition g=h?f, where h:k^m?k is an arbitrary function. In the case that k is algebraically closed of characteristic 0 and f is surjective, we will show that g=h?f implies that h is a polynomial.
