摘要
设 ω 为加倍权重,且 0 < p ≤ q < ∞ {0<p\leq q<\infty} 。在 ℂ n {mathbb{C}^{n} 的单位球中研究了从加权伯格曼空间 A ω p {A^{p}_{\omega}} 到 A ω q {A^{q}_{\omega}} 的黎曼-斯蒂尔杰斯算子 T g {T_{g}} 的基本规范。} .
Essential norm of Riemann–Stieltjes operator on weighted Bergman spaces with doubling weights
Let ω be a doubling weight and 0<p≤q<∞{0<p\leq q<\infty}. The essential norm of Riemann–Stieltjes operator Tg{T_{g}} from the weighted Bergman space Aωp{A^{p}_{\omega}} to Aωq{A^{q}_{\omega}} was investigated in the unit ball of ℂn{\mathbb{C}^{n}}.
期刊介绍:
The Georgian Mathematical Journal was founded by the Georgian National Academy of Sciences and A. Razmadze Mathematical Institute, and is jointly produced with De Gruyter. The concern of this international journal is the publication of research articles of best scientific standard in pure and applied mathematics. Special emphasis is put on the presentation of results obtained by Georgian mathematicians.
