✦ Synopsis


Abhyankar had shown that in order to solve the Jacobian Conjecture, it suffices to rule out the existence of Jacobian pairs with mixed leading form. Assume that such a pair {,f,g} exists. Following Abhyankar, consider the Laurent series expansion of {f,g} at infinity. Part of the coefficients of the series becomes invariants of certain group action. We also obtain several old results proved by Moh by investigating the associated group action. @ 1997
