Zusammenfassung: For a polynomial map $f : k^n \to k^m$ ($k$ a field), we investigate those polynomials $g \in k[t_1,\ldots, t_n]$ that can be written as a composition $g = h \circ f$, where $h: k^m \to k$ is an arbitrary function. In the case that $k$ algebraically closed of characteristic $0$ and $f$ is surjective, we will show that $g = h \circ f$ implies that $h$ is a polynomial.
