Abstract

Let F:\Bbb Cn→\Bbb Cn be a polynomial mapping with a non vanishing Jacobian. If the set SF of non-properness of F is smooth, then F is a surjective mapping. Moreover, the set SF can not be connected (this is the Nollet-Xavier Conjecture). Additionally, if n=2, then the set SF of non-properness of F cannot be a curve without self-intersections.
