Abstract

Let Ω\Omega be homogeneous of degree zero, have mean value zero and integrable on the unit sphere, and μΩ\mu_{\Omega} be the higher-dimensional Marcinkiewicz integral defined by μΩ(f)(x)=(0xytΩ(xy)xyn1f(y)dy2dtt3)1/2.\mu_\Omega(f)(x)= \Big(\int_0^\infty\Big|\int_{|x-y|\leq t}\frac{\Omega(x-y)}{|x-y|^{n-1}}f(y)dy\Big|^2\frac{dt}{t^3}\Big)^{1/2}. In this paper, the authors establish a bilinear sparse domination for μΩ\mu_{\Omega} under the assumption ΩL(Sn1)\Omega\in L^{\infty}(S^{n-1}). As applications, some quantitative weighted bounds for μΩ\mu_{\Omega} are obtained.
