Estimates for the multiple singular integrals via extrapolation Meng Qu School of Mathematical and Computer Sciences Anhui Normal University Wuhu 241002 People s Republic of China Corresponding author qumeng@ Abstract This paper is devoted to the study on the Lp estimates for the multiple singular integrals with rough kernels on product spaces Rn X Rm n m 2 . By means of extrapolation method and Fourier transform estimate we prove that the multiple singular integral operators are bounded on Lp Rn X Rm for the kernel functions 2 L log L 2 Sn 1 X Sm 1 h 2 Aa R X R a 2 1 2 . Furthermore we prove that when 2 L log L 2 S 1 X S 1 and h satisfying a log type .
