关于${\mathbb C}^2$中管域Kobayashi双曲性的充要条件

On necessary and sufficient conditions for the Kobayashi hyperbolicity of tube domains in ${\mathbb C}^2$

Alexander Isaev

摘要:

本文讨论了${\mathbb C}^2$中的管域,其中全纯全纯包不等于整个空间。我们构造了一些例子,证明了对于这类域,M。Jarnicki和P. Pflug不能用它的较弱的“仿射”变体来代替,这是已知的双曲性的必要条件。因此,我们得出了一个有点出乎意料的结论,即在上述类别中的区域是Kobayashi双曲的障碍不仅仅是“仿射”。

英文摘要:

This note concerns tube domains in ${\mathbb C}^2$ with the envelope of holomorphy not equal to the entire space. We construct examples showing that for such domains the sufficient condition for Kobayashi hyperbolicity due to M. Jarnicki and P. Pflug cannot be replaced by its weaker "affine" variant, which is known to be a necessary condition for hyperbolicity. Thus, we arrive at the somewhat unexpected conclusion that the obstructions for a domain in the above class to be Kobayashi hyperbolic are not just "affine".
