关于有界对称域之间的真全纯映射

On proper holomorphic maps between bounded symmetric domains

Shan Tai Chan

摘要:

研究了有界对称域$D$和$Ω$之间的真全纯映射.特别地,当$D$和$Ω$具有相同的秩$\ge 2$,使得$D$的所有不可约因子都具有秩$\ge 2$时,我们证明了从$D$到$Ω$的任意真全纯映射是关于$D$和$Ω$的某些典型Kähler度量的全测地全纯等距嵌入.我们还得到了关于全纯映射$F:D\to Ω$的一些结果,这些全纯映射把$D$的极小圆盘恰当地映射到$Ω$的秩- $1$特征对称子空间中.另一方面,在$D$和$Ω$上的一定秩条件下,得到了关于$D$和$Ω$之间的半积真全纯映射的新的刚性结果.

英文摘要:

We study proper holomorphic maps between bounded symmetric domains $D$ and $Ω$. In particular, when $D$ and $Ω$ are of the same rank $\ge 2$ such that all irreducible factors of $D$ are of rank $\ge 2$, we prove that any proper holomorphic map from $D$ to $Ω$ is a totally geodesic holomorphic isometric embedding with respect to certain canonical Kähler metrics of $D$ and $Ω$. We also obtain some results regarding holomorphic maps $F:D\to Ω$ which map minimal disks of $D$ properly into rank-$1$ characteristic symmetric subspaces of $Ω$. On the other hand, we obtain new rigidity results regarding semi-product proper holomorphic maps between $D$ and $Ω$ under a certain rank condition on $D$ and $Ω$.
