1维奇异边界交叉定理

Boundary cross theorem in dimension 1 with singularities

Peter Pflug, Viet-Anh Nguyen

摘要:

令$D$和$G$是$\C,$中的开放单位盘的副本,令$A$(分别为$B$)是$\partial D$的可测量子集(分别为$\partial G$),令$W$是2-fold cross $\big((D\cup A)\times B\big)\cup \big(A\times(B\cup G)\big),$,令$M$是$W.$的一个相对闭子集。纤维离散)和$M\cap (A\times B)=\varnothing.$我们确定$W\setminus M$的“全纯包络“$\hat{W\setminus M}$,在这个意义上,任何局部有界的$W\setminus M,$上的函数在$A\times B,$上可测,并分别在$\big((A\times G) \cup (D\times B)\big)\setminus M$上全纯“扩展”到$\hat{W\setminus M}.$上全纯的函数

英文摘要:

Let $D$ and $G$ be copies of the open unit disc in $\C,$ let $A$ (resp. $B$) be a measurable subset of $\partial D$ (resp. $\partial G$), let $W$ be the 2-fold cross $\big((D\cup A)\times B\big)\cup \big(A\times(B\cup G)\big),$ and let $M$ be a relatively closed subset of $W.$ Suppose in addition that $A$ and $B$ are of positive one-dimensional Lebesgue measure and that $M$ is fiberwise polar (resp. fiberwise discrete) and that $M\cap (A\times B)=\varnothing.$ We determine the "envelope of holomorphy" $\hat{W\setminus M}$ of $W\setminus M$ in the sense that any function locally bounded on $W\setminus M,$ measurable on $A\times B,$ and separately holomorphic on $\big((A\times G) \cup (D\times B)\big)\setminus M$ "extends" to a function holomorphic on $\hat{W\setminus M}.$
