Let $\phi = (f,g): C^2 \rightarrow C^2$ be a polynomial map of the plane over the field C of complex numbers with its Jacobian nonzero constant. The Jacobian conjecture asserts that $\phi$ must be an automorphism. We say that a point $P_infty \in P^2 \C^2$ of the complex projective plane P^2 is a `quasifinite' (w.r.t. \phi)$ if there exists a sequence $\{P_i\}$ in $C^2 \in P^2$ converging to $P_\infty$ such that the image $\{\phi(P_i)\}$ converges to a point in C^2. In this talk I will show that the conjecture holds if any only if there is no quasifinite point. |
