DESCRIPTION:TITLE / TITRE :\n\nSymplectic non-squeezing for the KdV and fif
 th-order KdV equations\n\nABSTRACT /RESUME \n\nIn this talk we prove that 
 the first two members of the KdV hierarchy have the non-squeezing property
 \, that is\, they cannot map a ball in the symplectic space H^{-\frac{1}{2
 }} wholly inside a thinner cylinder. This is an infinite-dimensional analo
 gue of Gromov's famous symplectic non-squeezing theorem. Our proof relies 
 on an approximation scheme by finite-dimensional Hamiltonian systems that 
 exploits the complete integrability of these equations.\n\nZoom Meeting :
