A note on variation continuity for multilinear maximal operators

Xiao Zhang

Shandong University of Science and Technology

Abstract

This note is devoted to establishing the variation continuity of the one-dimensional discrete uncentered multilinear maximal operator. The above result is based on some refine variation estimates of the above maximal functions on monotone intervals. The main result essentially improves some known ones.

Keywords: Discrete multilinear maximal operator, bounded variation, continuity
