| Abstract： |
Let (X , d, μ) be a space of homogeneous type, in the sense of Coifman and
Weiss, and ? : X × [0, ∞) → [0, ∞) satisfy that, for almost every x ∈ X , ?(x, ·) is an
Orlicz function and that ?(·, t) is a Muckenhoupt A∞(X ) weight uniformly in t ∈ [0, ∞).
In this article, the authors first establish a new molecular characterization, associated
with admissible sequences of balls on X , of the Musielak-Orlicz Hardy space H ?(X ). As
an application, the authors also obtain the boundedness of Calder′on-Zygmund operators
from H ?(X ) to H ?(X ) or to the Musielak-Orlicz space L?(X ). The main novelty of these
results is that, in the proof of the boundedness of Calder′on-Zygmund operators on H ?(X ),
the authors get rid of the dependence on the reverse doubling property of μ by using this
new molecular characterization of H ?(X ) |
