### Abstract

We consider the initial value problem for nonlinear Schödinger equations, where ∂ = ∂_{x} = ∂/∂x and F: C^{4} → C is a polynomial having neither constant nor linear terms. Without a smallness condition on the data u_{0}, it is shown that (+) has a unique local solution in time if u_{0} is in H^{3, 0} ∩ H^{2, 1}, where H^{m, s} = {f ∈ S’ ∥f∥^{m, s} = ∥(1 + x^{2})^{s/2} (1-Δ)f∥
