全纯函数和刚性的精确维数估计

Sharp Dimension Estimates of Holomorphic Functions and Rigidity

Bing-Long Chen, Xiao-Yong Fu, Le Yin, Xi-Ping Zhu

摘要:

设$M^n$是复维数为$n$且具有非负全纯双截曲率的完备非紧K $\ddot{a}$ hler流形.用$\mathcal{O}$ $_d(M^n)$表示$M^n$上次数至多为$d$的多项式增长的全纯函数的空间。本文证明了对所有的$d>0$都有$$dim_{\mathbb{C}}{\mathcal{O}}_d(M^n)\leq dim_{\mathbb{C}}{\mathcal{O}}_{[d]}(\mathbb{C}^n),$$,且对某个正整数$d$相等当且仅当$M^n$与$\mathbb{C}^n$全纯等距.当它的体积增长不是最大的或者它的Ricci曲率在某处为正时,我们也得到了明显改进的维数估计。

英文摘要:

Let $M^n$ be a complete noncompact K$\ddot{a}$hler manifold of complex dimension $n$ with nonnegative holomorphic bisectional curvature. Denote by $\mathcal{O}$$_d(M^n)$ the space of holomorphic functions of polynomial growth of degree at most $d$ on $M^n$. In this paper we prove that $$dim_{\mathbb{C}}{\mathcal{O}}_d(M^n)\leq dim_{\mathbb{C}}{\mathcal{O}}_{[d]}(\mathbb{C}^n),$$ for all $d>0$, with equality for some positive integer $d$ if and only if $M^n$ is holomorphically isometric to $\mathbb{C}^n$. We also obtain sharp improved dimension estimates when its volume growth is not maximal or its Ricci curvature is positive somewhere.
