Abstract

In this paper, we systematically study weighted jump and variational inequalities for rough operators. More precisely, we show some weighted jump and variational inequalities for the families T:={Tε}ε>0\mathcal T:=\{T_\varepsilon\}_{\varepsilon>0} of truncated singular integrals and MΩ:={MΩ,t}t>0\mathcal M_{\Omega}:=\{M_{\Omega,t}\}_{t>0} of averaging operators with rough kernels, which are defined respectively by Tεf(x)=y>εΩ(y)ynf(xy)dy T_\varepsilon f(x)=\int_{|y|>\varepsilon}\frac{\Omega(y')}{|y|^n}f(x-y)dy and MΩ,tf(x)=1tny<tΩ(y)f(xy)dy,M_{\Omega,t} f(x)=\frac1{t^n}\int_{|y|<t}\Omega(y')f(x-y)dy, where the kernel Ω\Omega belongs to Lq(Sn1)L^q(\mathbf S^{n-1}) for q>1q>1.
