Let X be a Banach space and ψ an analytic self-map of D. We characterize the weak compactness of the composition operator C〓 on the vectorvalued Nevanlinna classes N and N〓.

给出了向量值解析函数空间N与N〓上的复合算子C〓的弱紧性的刻画，这里X是一个Banach空间。

Iii By using the well-known properties of the dela vallee-poussin summability kernels and the pass principle of weakly compact operator, we study the weak compactness of C〓 on vector-valued analytic function spaces H〓, B〓, N and N〓, establish some connections between the weak compactness of composition operators and the structure properties of Banach spaces. These generalize and unify the corresponding results in the scalar-valued setting and enrich the content of the study of composition operator in another way.
