本文研究了B^α(Bm)到BMOA(Bn)上的复合算子.利用Carleson测度的等价条件,得到了B^α(Bm)到BMOA(Bn)上复合算子的有界和紧性的特征,推广了Bloch空间上复合算子的相应结果.
In this article, we study the composition operator CФ from B^α(Bm) to BMOA(Bn). Using the equivalent conditions of Carleson measure, we get the characterizations of boundedness and compactness of composition operator CФ from B^α(Bm) to BMOA(Bn) and extend the corresponding results of composition operator CФ on Bloch spaces.
