摘要
The paper investigate a necessary and sufficient condition for the composition operator from harmonic Lipschitz spaces Lip(H)(alpha), (0 < alpha < 1) into weighted harmonic Zygmund spaces Z(H)(beta), (0 < beta < infinity) to be bounded and compact on the open unit disk. As an application, it estimates the essential norms of such an operator from Lip(H)(alpha) into Z(H)(beta) spaces.
