Electronic Journal of Differential Equations, 2016(34), pp. 1-8.1072-6691https://hdl.handle.net/10877/16908We study the Cauchy problem for the cubic hyperbolic Schrödinger equation in two space dimensions. We prove existence of analytic global solutions for sufficiently small and exponential decaying data. The method of proof depends on the generalized Leibniz rule for the generator of pseudo-conformal transform acting on pseudo-conformally invariant nonlinearity.Text8 pages1 file (.pdf)enAttribution 4.0 InternationalNonlinear Schrödinger equationNon elliptic Schrödinger equationAnalytic smoothing effectGlobal solutionArticle
