We consider the Cauchy problem for the one-dimensional periodic cubic non- linear Schrodinger equation (NLS) with initial data below L 2 . In particular, we exhibit nonlinear smoothing when the initial data are randomized. Then, we prove local well- posedness of NLS almost surely for the initial data in the support of the canonical Gaussian measures on H s (T) for each s > − 1 , and global well-posedness for each s > − 1 12 .
