该研究证明了解析Besov空间$B_{p,p}^{1/p}(\mathbb{C}_+^n)$连续嵌入Chang–Fefferman乘积BMO,进而得出有限Schatten类小Hankel算子具有乘积BMO符号的结论,还给出Fejér均值的相关条件。
AI 中文摘要
我们证明,对任意有限n和1≤p<∞,解析Besov空间$B_{p,p}^{1/p}(\mathbb{C}_+^n)$连续嵌入Chang–Fefferman乘积BMO。因此,有限Schatten类中的每个小Hankel算子都有乘积BMO符号。证明采用光滑乘积小波与二进矩形的估计,还给出Fejér均值的一个条件,该条件可得到多圆柱上有界Hankel算子的BMO符号。
英文摘要
We prove that the analytic Besov space $B_{p,p}^{1/p}(\C_+^n)$ embeds continuously into Chang--Fefferman product BMO for every finite $n$ and $1\le p<\infty$. Consequently, every small Hankel operator in a finite Schatten class has a product BMO symbol. The proof uses smooth product wavelets and an estimate for dyadic rectangles. We also give a condition on Fejér means that yields a BMO symbol for a bounded Hankel operator on the polydisc.
