The initial value problem for the L2 critical semilinear Schrödinger equation in ℝ,n, n ≥ 3 is considered. We show that the problem is globally well posed in Hs(ℝ n) when 1 > s > & √7-1/3 for n = 3, and when 1 > s > -(n-2)+√(n-2)2+8(n-2)/4 for n > 4 We use the "I-method" combined with a local in time Morawetz estimate.
