Let f is an element of C-1 (R-2, R-2), f(0) = 0. The Jacobian Conjecture st
ates that if for any x is an element of R-2, the eigenvalues of the Jacobia
n matrix Df(x) have negative real parts, then the zero solution of the diff
erential equation x (over dot) = f(x) is globally asymptotically stable. In
this paper we prove that the conjecture is true.
