Hilbert球的自同构刻画

Characterization of the Hilbert ball by its Automorphisms

Kang-Tae Kim, Daowei Ma

摘要:

本文证明了可分希尔伯特空间中具有$C^2$光滑强伪凸边界点且自同构轨道在其上聚集的每个区域,如$\cH$,都与$\cH$的单位球双全纯.这是Wong-Rosay定理到无限维可分希尔伯特空间的完全推广。我们在这里的工作是对Kim/Krantz [KIK]的先前工作和Byun/Gaussier/Kim [BGK]在无限维中的后续改进的改进。

英文摘要:

We show in this paper that every domain in a separable Hilbert space, say $\cH$, which has a $C^2$ smooth strongly pseudoconvex boundary point at which an automorphism orbit accumulates is biholomorphic to the unit ball of $\cH$. This is the complete generalization of the Wong-Rosay theorem to a separable Hilbert space of infinite dimension. Our work here is an improvement from the preceding work of Kim/Krantz [KIK] and subsequent improvement of Byun/Gaussier/Kim [BGK] in the infinite dimensions.
