线性映射紧扰动的infinite dimensional Gromov非压缩性的另一种证明

An alternative proof of infinite dimensional Gromov's non-squeezing for compact perturbations of linear maps

Lorenzo Rigolli

摘要:

本文讨论了将Gromov非压缩定理推广到无限维Hilbert相空间的问题。根据Hyndham和Zehnder关于有限维非压缩的证明,我们恢复了Kuksin关于辛线性映射的非线性紧扰动的辛同态的无限维非压缩结果.我们还表明,无限维非压缩问题,在充分的一般性,可以重新制定的问题,找到一个合适的Palais-Smale序列的一个杰出的哈密顿作用泛函。

英文摘要:

This paper deals with the problem of generalising Gromov's non squeezing theorem to an infinite dimensional Hilbert phase space setting. By following the lines of the proof by Hofer and Zehnder of finite dimensional non-squeezing, we recover an infinite dimensional non-squeezing result by Kuksin for symplectic diffeomorphisms which are non-linear compact perturbations of a symplectic linear map. We also show that the infinite dimensional non-squeezing problem, in full generality, can be reformulated as the problem of finding a suitable Palais-Smale sequence for a distinguished Hamiltonian action functional.
