Abstract
In this paper, we study the weighted jump function and variation of hypersingular integral operators with rough kernels which are defined as
where α ≥ 0, Ω is an integrable function on the unit sphere \({\mathbb S^{n - 1}}\) satisfying certain cancellation conditions. More precisely, we show that for 1 < p < ∞, the jump function and variation of the family of truncated hypersingular integrals {TΩ,α, ε}ε>0 extends to bounded operators from the weighted Sobolev space L pα (w) to the weighted Lebesgue space Lp(w) with \(\Omega \,\,{L^q}({\mathbb S^{n - 1}})\) where q > 1.
