Abstract
In this paper we prove a discrete version of Tanaka's theorem for the Hardy-Littlewood maximal operator in dimension , both in the non-centered and centered cases. For the non-centered maximal operator we prove that, given a function of bounded variation,
where represents the total variation of . For the centered maximal operator we prove that, given a function such that ,
This provides a positive solution to a question of Hajłasz and Onninen in the discrete one-dimensional case.
