Let and denote the normalized Lebesgue measure on . For functions defined on , consider the multilinear operator given by
In this paper, we obtain necessary and sufficient conditions on exponents and for which the operator is bounded from , where . This generalizes the results obtained in (Bak and Shim, J. Funct. Anal. 157 (1998) 534–553; Oberlin, Trans. Amer. Math. Soc. 310 (1988) 821–835).
