| Resumo | |
We obtain a new theorem for the non-properness set S-f of a non-singular polynomial mapping f : C-n -> C-n. In particular, our result shows that if f is a counterexample to the Jacobian conjecture, then S-f boolean AND Z not equal empty set, for every hypersurface Z dominated by Cn-1 on which some non-singular polynomial h (:) C-n -> C is constant. Also, we present topological approaches to the Jacobian conjecture in C-n. As applications, we extend bidimensional results of Rabier, Le and Weber to higher dimensions. (AU) | |
