Abstract:In this paper, the authors established the (Mpq (Rn), Lip(α+β-n/q)(Rn))-boundedness and (Mpq (Rn), BMO(Rn))-boundedness of the multilinear commutator L-α/2→b,which generatedby a finite family of locally integral functions →b= (b1, b2,..., bm) and the generalized fractional integral L-α/2 for 0 < α < n, is defined by L-α/2→bf = bm,..., b2b1, L-α/2]],..., ]f, where m ∈ Z+ and bi ∈ Lipβi (0 <βi < 1) for (1 ≤ i ≤ m).
Keywords:multilinear commutator  generalized fractional integrals  lipschitz function space
