Note on the Jacobian condition and the
non-proper value set
Annales Polonici Mathematici, Tome 84 (2004) no. 3, pp. 203-210
We show that the non-proper value set of a polynomial map $(P,Q): {{\mathbb C}}^2\rightarrow {{\mathbb C}}^2$ satisfying the Jacobian condition $\mathop {\rm det}D(P,Q)\equiv {\rm const}\not =0$, if non-empty, must be a plane curve with one point at infinity.
Keywords:
