Abstract

In this paper, we study the Cauchy problem for the quadratic derivative nonlinear Schrödinger equation {iut + UXX = (Ũx)2, (t, x) ε R2, {u(0, x) = u0, x ε R. We suppose that the initial data are small in the weighted Sobolev space H3,1(R) then we prove that there exist global in time small solutions to the Cauchy problem (*). We study the large time behavior of solutions and construct the modified asymptotics for large time values.
