On rigid rational cuspidal plane curves
by S. Yu. Orevkov and M. G. Zaidenberg
Uspekhi Mat. Nauk, 51(1996), no. 1, 149-150 (in Russian); English translation: Russian Math. Surveys, 51(1996), 179-180
Abstract: A plane curve is called cuspidal if it has one branch at each singularity. We prove that a projectively rigid rational cuspidal curve has at most 9 singular points.

In English translation, some pluses look as minuses because of the quality of copy machine. So, see the Russian version for the definition of P(t) and Q(t) on p. 128.

Abstract: It is proved that the Jacobian of a 3-fold polynomial mapping of the complex plane into itself cannot be constant, i.e. a counter-example to the Jacobian Conjecture in dimension 2 cannot be realised by a 3-fold mapping
