Polynomial and regular images of \(\mathbb R^n\). (English) Zbl 1213.14109

Summary: We obtain new necessary conditions for an\(n\)-dimensional semialgebraic subset of \(\mathbb R^n\) to be a polynomial image of \(\mathbb R^n\) . Moreover, we prove that a large family of planar bidimensional semialgebraic sets with piecewise linear boundary are images of polynomial or regular maps, and we estimate in both cases the dimension of their generic fibers.
