Abstract. We obtain sufficient and necessary conditions on weight functions s 1 (t), . . . , s m (t) and ψ(t) so that the weighted multilinear HardyCesàro operatorThe sharp bounds are also obtained and these results hold for both cases 0 < p < 1 and 1 ≤ p < ∞. We give a sufficient condition so that if symbols b 1 , . . . , b m are Lipschitz, then the commutator of the weighted Hardy-Cesàro operatorp,q (ω) for both cases 0 < p < 1 and 1 ≤ p < ∞. By these we extend and strengthen previous results deu to Tang, Xue, and Zhou [16].
