研究了上半平面Bloch空间和上半平面增长型空间上的复合算子,证明了一类Bloch空间上复合算子的谱是闭单位圆盘,并刻画了一类增长型空间上复合算子的谱.
It was discussed the composition operators on the Bloch space and the growth-type space on the upper half-plane.It was proved that the spectrum of a class of composition operators on the Bloch space was the closed unit disk in the complex plane,and the spectrums of a class of composition operators on the growth space were characterized.
