球上有界全纯函数的模

Moduli of bounded holomorphic functions in the ball

B. Korenblum, J. McCarthy

摘要:

本文证明了在$\cd$中的单位球面上存在连续的非负函数$g$,$d \geq 2$,它的对数关于勒贝格测度可积,并且它只在一点处为零,但使得在单位球面上没有一个非零有界解析函数$m$,其边界值$m^\star$,$|m^\star| \leq g$几乎处处为零.证明分析了球的Hardy空间上的共解析Toeplitz算子的公共值域。

英文摘要:

We prove that there is a continuous non-negative function $g$ on the unit sphere in $\cd$, $d \geq 2$, whose logarithm is integrable with respect to Lebesgue measure, and which vanishes at only one point, but such that no non-zero bounded analytic function $m$ in the unit ball, with boundary values $m^\star$, has $|m^\star| \leq g$ almost everywhere. The proof analyzes the common range of co-analytic Toeplitz operators in the Hardy space of the ball.
