Abstract
In this paper, the authors establish the (Lp(μ), Lq(μ))-type estimate for fractional commutator generated by fractional integral operators Tα with Lipschitz functions (b ∈ Lipβ (μ)), where 1 <p < 1/(α + β) and 1/q = 1/p– (α + β), and obtain their weak (L1(μ), L1/(1–α–β) (μ))-type. Moreover, the authors also consider the boundedness in the case that 1 /(α+β) < p < 1/α, 1/α ≤ p ≤ ∞ and the endpoint cases, namely, p = 1/(α + β).
