C^2中具有非紧自同构群的双曲Reinhardt域
Hyperbolic Reinhardt Domains in C^2 with Noncompact Automorphism Group
摘要:
本文给出了C^2中双曲Reinhardt域D的一个显式刻画,使得:(i)D具有C^k-光滑边界,其中k大于1;(ii)D与坐标复线$\{z_1=0\}$,$\{z_2=0\}$中的至少一条相交;(iii)D具有非紧自同构群.我们还给出了一个例子,解释了为什么这样的设置是自然的双曲域的情况下,一个例子表明,在C^n的情况下,n大于或等于3,本质上是更复杂的比在C^2。
英文摘要:
We give an explicit description of hyperbolic Reinhardt domains D in C^2 such that: (i) D has C^k-smooth boundary for some k greater than or equal to 1, (ii) D intersects at least one of the coordinate complex lines $\{z_1=0\}$, $\{z_2=0\}$, and (iii) D has noncompact automorphism group. We also give an example that explains why such a setting is natural for the case of hyperbolic domains and an example that indicates that the situation in C^n for n greater than or equal to 3 is essentially more complicated than that in C^2.
