摘要

The local well-posedness with small data in H-s (R-n) (s >= 3 + max(n/2,1(+))) for the Cauchy problem of the fourth order nonlinear Schrodinger equations with the third order derivative nonlinear terms were obtained by Huo and Jia [17]. In this paper we show its global well-posedness with small data in the modulation space M-2,1(7/2) and in Sobolev spaces Hn/2+7+/2. For a special nonlinear term containing only one third order derivative, we can show its global well posedness in M-2,1(7/2) H(n+1+)/2. (C) 2015 Elsevier Masson SAS. All rights reserved.
