Yitang Zhang who became famous recently thanks to brake-through in the twins conjecture wrote his PhD thesis on the plane Jacobian conjecture where he gave an estimate of the geometric degree of the corresponding mapping of a plane via algebraic degrees of the images of the coordinate functions. In my talk I'll explain how to gets a better estimate via the Newton polytope approach.
