摘要
Given α, 0 < α < n, and b ∈ BMO, we give sufficient conditions on weights for the commutator of the fractional integral operator, [b, Iα], to satisfy weighted endpoint inequalities on ℝn and on bounded domains. These results extend our earlier work [3], where we considered unweighted inequalities on ℝn.
