1、南京师范大学博士学位论文单位球上的α-Bloch空间及其间的复合算子姓名:张敏珠申请学位级别:博士专业:基础数学指导教师:陈怀惠20070301摘要本文研究单位球上的n.Bloch空间之间的复合算子.乘积算子和日*到∞Bloch空间的加权复合算子.在本文中,首先引入新的度量口(口),给出了单位球上的a-Bloch函数的等价范数,推广TTimoney关于单位球上的Bloch函数的结果.同时也给出了单位球上的d、a-Bloch函数的等价刻划.其次借助度量嚣(口),我们完整地研究了单位球上a-Bloch空间之间的复合算子的有界性和紧性,得到了相应的充分必要条件
2、.同时还研究了单位球上日。到*B10ch空问的加权复合算子的有界性和紧性,也得到了相应的充分必要条件.改进了李颂孝和S.Stevid的相关结果.最后,我们完整地讨论了单位球上a-Bloch空间之间的乘积算子的下有界性.得到了下有界性的充分必要条件.关键词:a-Bloch空间,上P,复合算子,乘积算子,加权复合算子,有界性,紧性,下有界性.VAbstractInthisthesis,weinvestigatecompositionoperatorsandmultiplicationoperatorsbetweenn—Blochspaces,andweigh
