The equivalent norms and the Gleason's problem on μ -Zygmund spaces in CnCn

Let μ   be a normal function on [0,1)[0,1). In this paper, the authors give four equivalent norms of the functions in the μ  -Zygmund space Zμ(B)Zμ(B) on the unit ball B   in CnCn. At the same time, the authors prove that the Gleason's problem is solvable on Zμ(B)Zμ(B).
