摘要
We consider maximal functions M f (x, theta), singular integrals H f (x, theta), and maximal singular integrals H-* f (x, theta) on R-n x Sn-1 associated with homogeneous curves, for functions f on R-n. We prove certain weighted mixed norm estimates for them. These results are applied to the theory of singular integrals with variable kernels via the method of rotations of Calderon-Zygmund.
