ABHYANKAR 82nd BIRTHDAY CONFERENCE 

SPEAKER: Ignacio Luengo (Madrid)

TITLE: Geometric properties of common dicritical of jacobian pairs

ABSTRACT: A jacobian pair  (f,g) is a pair of polynomials in the plane such that
its jacobian Jac(f,g) is constant. We give the structure of the common
diacriticals of Jacobian pairs that are not automorphisms. This can be  
useful for the proof of the Jacobian conjecture of the plane.
