We study the Cauchy problem for the following Schrödinger equation in R n (n∈ N): i∂ t u+ 1 2 Δu= V 1 u+(V 2∗¦ u¦ 2) u,(t, x)∈ R× R n, u (0)= φ, x∈ R n,(∗∗) where V 1= V 1 (x)= λ 1¦ x¦− γ1, V 2= V 2 (x)=∑ k= 2 3 λ k¦ x¦− γk, λ k∈ R (1⩽ k⩽ 3), 0< γ 1< min (2, n 2), 0< γ 2, γ 3< min (2, n). We prove the existence, uniqueness, and smoothing effect of global solutions of (∗∗) with φ not necessarily in the Sobolev space H 1 (R n).
