Abstract

Suppose that ΩL(Sn1)\Omega \in L^{\infty}(\mathbb{S} ^{n-1}) is homogeneous of degree zero with mean value zero. Then we consider a fractional type Marcinkiewicz integral operator μΩ,βf(x)=(0xytΩ(xy)xyn1βf(y)dy2dtt3)12,0<β<n.\mu_{\Omega ,\beta }f(x) = \left ( \int_{0}^{\infty } \left | \int_{\left | x-y \right |\le t }^{} \frac{\Omega (x-y)}{\left | x-y \right |^{n-1-\beta } } f(y)dy \right | ^{2}\frac{dt}{t^3} \right )^{\frac{1}{2} },\quad 0<\beta<n. Our main contribution is the quantitive weighted result of the classical Marcinkiewicz integral μΩ\mu_{\Omega} proved by Hu and Qu [Math. Ineq. appl., 22(2019), 885-899] can be recovered from the quantitative weighted estimates of μΩ,β\mu_{\Omega,\beta} in this paper when β0+\beta\to 0^+. As inference, we also gives the uniform quantitive weighted bounds for the corresponding fractional commutators of μΩ,β\mu_{\Omega,\beta} when β0+\beta \rightarrow 0^+.
