Abstract

We study the elliptic-hyperbolic Davey-Stewartson system , where c1, c2 ∈ R, u is a complex valued function and φ is a real valued function. The system can be translated to nonlocal nonlinear Schrödinger equations after a rotation and a rescaling, where c0, c1, c2 ∈ C. Our purpose in this paper is to prove that if the norm ||(π2j=1 cosh θxj)u0||3,0 + ||(π2j=1 cosh θxj)u0||0,3 for θ ≠ 0 is sufficiently small, then small solutions of (NLS) exist and become analytic with respect to x for any t ≠ 0 . Here we denote the weighted Sobolev space by Hm,s = {φ ∈ L2; ||φ||m,s =(1+x21+x22)s/2(1-∂2x1-∂2x2)m/2φ|| < infin; }, m, s ∈ R+.
