The Jacobian Conjecture can be generalized and is established : Let S be a polynomial ring over a field of characteristic zero in finitely may variables. Let T be an unramified, finitely generated extension of S with T = k . Assume that T is a UFD. Then T = S. The Jacobian Conjecture is the following : If f1, · · · , fn be elements in a polynomial ring k[X1… CONTINUE READING
