Abstract

We prove a generalization of Gromov's symplectic non-squeezing theorem for\nthe case of Hilbert spaces. Our approach is based on filling almost complex\nHilbert spaces by complex discs partially extending Gromov's results on\nexistence of J-complex curves. We apply our result to the flow of the\ndiscrete nonlinear Schr "odinger equation.\n
