论文摘要
在本文中,我们介绍并研究了一些从功能空间作用的希尔伯特型运算符到序列中。我们为这些希尔伯特型操作员的界限和紧凑性提供了一些足够和必要的条件。同样,在某些特殊情况下,我们获得了某些希尔伯特型运营商规范的尖锐估计。
In this paper we introduce and study some Hilbert-type operators acting from the function spaces into the sequence spaces. We give some sufficient and necessary conditions for the boundedness and compactness of these Hilbert-type operators. Also, for some special cases, we obtain the sharp estimates for the norms of certain Hilbert-type operators.
