Symplectic non-squeezing for the discrete nonlinear Schrodinger equation Tumanov, Alexander
Description
The celebrated Gromov's non-squeezing theorem of 1985 says that the unit ball $B^n$ in $C^n$ can be symplectically embedded in the "cylinder" $rB^1 \times C^{n-1}$ of radius r only if $r\ge 1$. Hamiltonian differential equations provide examples of symplectic transformations in infinite dimension. Known results on the non-squeezing property in Hilbert spaces cover compact perturbations of linear symplectic transformations and several specific non-linear PDEs, including the periodic Korteweg - de Vries equation and the periodic cubic Schr\"odinger equation. We prove a new version of the non-squeezing theorem for Hilbert spaces. We apply the result to the discrete nonlinear Schr\"odinger equation. This work is joint with Alexander Sukhov.

Hamiltonian differential equations provide examples of symplectic
transformations in infinite dimension. Known results on the non-squeezing
property in Hilbert spaces cover compact perturbations of linear
symplectic transformations and several specific non-linear PDEs, including
the periodic Korteweg - de Vries equation and the periodic cubic
Schr\"odinger equation. We prove a new version of the non-squeezing
theorem for Hilbert spaces. We apply the result to the discrete nonlinear
Schr\"odinger equation. This work is joint with Alexander Sukhov.
