Sharp Maximal function estimates for Multilinear pseudo-differential operators of type (0,0)
arXiv:2405.02093
Abstract
In this paper, we study sharp maximal function estimates for multilinear pseudo-differential operators. Our target is operators of type (0, 0) for which a differentiation does not make any decay of the associated symbol. Analogous results for operators of type (Ï, Ï), 0 < Ï< 1, appeared in an earlier work of the authors, but a different approach is given for Ï= 0
