. We study bilinear rough singular integral operators L Ω associated with a function Ω on the sphere S 2 n − 1 . In the recent work of Grafakos, He, and Slav´ıkov´a [16], they showed that L Ω is bounded from L 2 × L 2 to L 1 , provided that Ω ∈ L q ( S 2 n − 1 ) for 4 / 3 < q ≤ ∞ with mean value zero. In this paper, we provide a generalization of their result. We actually prove L p 1 × L p 2 → L p estimates for L Ω under the assumption where 1 < p 1 , p 2 ≤ ∞ and 1 / 2 < p < ∞ with 1 /p = 1 /p… 



On commutators of singular integrals and bilinear singular integrals

LP estimates for multilinear singular integrals generalizing Calderon's commutator integral are obtained. The methods introduced involve Fourier and Mellin analysis. 1. In this paper we introduce new
