Abstract
It is proved that a class of multilinear singular integral operators with homogeneous kernels are bounded operators from the product spaces\(L^{p_1 } \times L^{p_2 } \times \cdots \times L^{p_k } (\mathbb{R}^n )\) to the Hardy spacesH r, (ℝn) and the weak Hardy spaceH r,∞ (ℝn. As an application of this result, the Lp,(ℝn) boundedness of a class of commutator for the singular integral with homogeneous kernels is obtained.
