Persistence of complete integrability in 1-d.
Abstract:
KAM theory for nearly integrable Hamiltonian systems has a long 60 more years of history.
Its influence on the general understanding of Classical Mechanics is tremendous.
Its extensions to small perturbations of integrable soliton equatios have been done
in many cases by Kuksin, Bourgain,Wayne, Deift, etc.. This talk will present some of their results
in the special cases of non-linear Schrodinger equations. We will try to present the flow of ideas
showing the existence of quasi-periodic solutions in these equations, pointing out the key conditions
and the key computations or estimates. All the complcated details will be left out.相關檔案:Poster-1021014.jpg
