摘要
We study a global existence in time of small solutions to the quadratic nonlinear Schrodinger equation in two space dimensions, (0.1) [GRAPHICS] where [GRAPHICS] lambda (j)k, mu (j)k is an element of C. We prove that if the initial data u 0 satisfy some analyticity and smallness conditions in a suitable norm, then the solution of the Cauchy problem (0.1) exists globally in time. Furthermore we prove the existence of the usual scattering states.
