Abstract
Let ɸ be an analytic map on the open unit disk D in the complex plane such that ɸ (D)⊂ D. The composition operator DCɸ : is deï¬ned by
DCɸ (f)=(foɸ) ′
In this paper, the boundedness and compactness of the composition opÂerator DCɸ from the weighted Bergman Nevanlinna spaces to Zygmund spaces are  investigated.
