Abstract
Let Ω ∈ L s (S n−1), s ≥ 1, be a homogeneous function of degree zero, and let σ (0 < σ < n) and b be Lipschitz or BMO functions. In this paper, we establish the boundedness of the commutators [b, T Ω,σ ], generated by a homogeneous fractional integral operator T Ω,σ and function b, on the Herz-type Hardy spaces with variable exponent.
