We consider the Cauchy problem for the cubic nonlinear Schrodinger equation {iu(t) + 1/2u(xx) = u(3), x is an element of R, t > 0, u(0, x) = u(0)(x), x is an element of R. (0.1) The aim of the present paper is to consider problem (0.1) in low-order Sobolev spaces, when the initial data u(0) is an element of H(alpha) boolean AND H(0,alpha) with alpha >1/2. In our previous paper [7] we proved the global existence of solutions to (0.1) if the initial data u(0) is an element of H(2) boolean AND H(0,2). Also we find the large-time asymptotics of solutions.
