The authors consider the classes of the univalent functions denoted by SH(β),SP and SP(α,β).On these classes,the univalence conditions for a general integral operator are studied.

In this paper, by Fourier transform estimates, Littlewood-Paley theory and approximation, the authors prove that if Ω∈(lnL)2 (Sn- 1), then the commutator generated by TΩ and CMO(Rn) function, and the corresponding discrete maximal operator, are compact on LP(Rn, |s|γp) for p∈ (1, ∞) and γp ∈ (-1, p-l)展开更多
