设和为分别作为三元组X和Y的单位球实现的有界对称域。本文利用上的全纯映射的Schwarz-Pick引理将朗道定理推广到上的全纯映射,并利用上的Bloch空间的采样集给出了上的Bloch空间和上的Bloch空间之间的复合算子下有界的一个必要条件,其中上的Bloch空间是从到的全纯映射。在复Hilbert球的情形下,我们还得到了Bloch空间之间复合算子的其它必要条件。利用Bloch空间的采样集,给出了Bloch空间上的复合算子和Bloch空间下有界的一个充分条件.在这种情况下,我们还给出了上和上的Bloch空间之间的复合算子在下有界的另一个充分条件。
Letandbe bounded symmetric domains realized as the unit balls of-triplesXandY, respectively. In this paper, we generalize the Landau theorem to holomorphic mappings onusing the Schwarz–Pick lemma for holomorphic mappings on. Next, we give a necessary condition for the composition operatorsbetween the Bloch spaces onandto be bounded below by using a sampling set for the Bloch space, whereis a holomorphic mapping fromto. We also obtain other necessary conditions for the composition operatorsbetween the Bloch spaces in the caseis a complex Hilbert ball. We give a sufficient condition for the composition operatorsbetween the Bloch spaces onandto be bounded below using a sampling set for the Bloch space. In the case, we also give another sufficient condition for the composition operatorsbetween the Bloch spaces onandto be bounded below.
