从$\mathbb C^n$中的单位球面到通过有限集的复直线的全纯扩张

Holomorphic extension from the unit sphere in $\mathbb C^n$ into complex lines passing through a finite set

Mark L. Agranovsky

摘要:

设$B^n$是$n$维单位复球,$a$和$b$是其闭包中的两个不同点。设$f$是复单位球面$\partial B^n.$上的实解析函数.设对任何与两点集$\{a,b\},$相交的复直线$L,$,函数$f$在截面$L \cap B^n.$上有一维全纯延拓,则$f$是$B^n$中全纯函数的边值.两个点不能被一个点取代。证明实质上使用了作者最近关于复平面上多解析函数的特征的结果。

英文摘要:

Let $B^n$ be the $n$-dimensional unit complex ball and let $a$ and $b$ be two distinct points in its closure. Let $f$ be a real-analytic function on the complex unit sphere $\partial B^n.$ Suppose that for any complex line $L,$ meeting the two points set $\{a,b\},$ the function $f$ admits one-dimensional holomorphic extension in the cross-section $L \cap B^n.$ Then $f$ is the boundary value of a function holomorphic in $B^n$. Two points can not be replaced by a single point. The proof essentially uses recent result of the author about characterization of polyanalytic functions in the complex plane.
