Two-weighted estimates of the multilinear fractional integral operator between weighted Lebesgue and Lipschitz spaces with optimal parameters
Given an m-tuple of weights v = (v 1 , . . ., vm), we characterize the classes of pairs (w, v) involved in the boundedness properties of the multilinear fractional integral operator frominto suitable Lipschitz spaces associated to a parameter δ, Lw(δ).Our results generalize some previous estimates not only …
