Abstract
It is proved that the Cauchy problem for the Kadomtsev-Petviashvili equation (KPII) is globally well-posed for initial data in anisotropic Sobolev spaces Hs0 (ℝ2) with s > -1/14. The extension of a local solution to a solution in an arbitrary interval is carried out by means of an almost conservation property of the Hs0 norm of the solution.
