摘要 Let k ∈ N.We prove that the lnultilinear operators of finite sums of products of singular integrals on R<sup>n</sup> are bounded from H K<sub>ql</sub><sup>αl·pl</sup>(R<sup>n</sup>)×…×HK<sub>qk</sub><sup>αk,pk</sup>(R<sup>n</sup>)into HK<sub>q</sub><sup>α,p</sup>(R<sup>n</sup>)if they have vanishing moments up to a certain order dictated by the target spaces.These conditions on vanishing moments satisfied by the multilinear operators are also necessary when α<sub>j</sub>(?)0 and the singular integrals considered here include the Calderón-Zygmund singular integrals and the fractional integrals of any orders.
