摘要

In this paper, we study weighted Besov spaces \( \mathcal {B}^\omega _p \) . By using Hardy inequalities, we derive significant weighted inequalities. Namely, we establish a Douglas-type formula for \( \mathcal {B}^\omega _p \) and identify an equivalent norm that depends only on the modulus of the function.
