关于C^n中射影壳的补

On the Complement of the Projective Hull in C^n

Blaine Lawson, John Wermer

摘要:

证明了若$K$是仿射簇O = P^n-D(其中D是射影超曲面)的紧致子集,且K是闭解析子簇V \subset O的紧致子集,则K的射影壳K^具有K^ \cap O包含在V中的性质.若V是光滑的1维的,则K^ \cap O也在O中闭.这个结果可以应用于圆盘代数中函数在C^2上的图。

英文摘要:

We prove that if $K$ is a compact subset of an affine variety O = P^n - D (where D is a projective hypersuface), and if K is a compact subset of a closed analytic subvariety V \subset O, then the projective hull K^ of K has the property that K^ \cap O is contained in V. If V is smooth and 1-dimensional, then K^ \cap O is also closed in O. The result has applications to graphs in C^2 of functions in the disk algebra.
