Hello, Joel Briancon (University of Nice, France) has solved the Jacobian problem in dimension 2: Let f,g be two polynomials in C[x,y] such that the Jacobian determinant is a nonzero complex number. We prove that the polynomial map (f,g):C2>C2 is an algebraic automorphism.
You can find the proof at http://arxiv.org/abs/math.AG/0512174
