泊松括号的2/3 -收敛速度

The 2/3 - convergence rate for the Poisson bracket

Lev Buhovsky

摘要:

本文介绍一种新的方法来逼近泊松括号的C^0 -刚性结果。利用这种方法,我们给出了泊松括号的一致范数在C^0扰动下的下半连续性的另一种证明。我们找到了半连续模的精确速率。这推广了Cardin-Viterbo,Zapolsky,Entov和Polterovich的结果。使用我们的方法,我们证明了一个C^0 -刚性结果,其精神与Humiliere的工作一致。我们还讨论了多线性微分算子的C^0 -刚性的一般性问题。

英文摘要:

In this paper we introduce a new method for approaching the C^0 - rigidity results for the Poisson bracket. Using this method, we provide a different proof for the lower semi-continuity under C^0 perturbations, for the uniform norm of the Poisson bracket. We find the precise rate for the modulus of the semi-continuity. This extends the previous results of Cardin-Viterbo, Zapolsky, Entov and Polterovich. Using our method, we prove a C^0 - rigidity result in the spirit of the work of Humiliere. We also discuss a general question of the C^0 - rigidity for multilinear differential operators.
