On a discrete version of Tanaka's theorem for maximal functions

Abstract:

In this paper we prove a discrete version of Tanaka's theorem for the Hardy-Littlewood maximal operator in dimension n = 1, both in the noncentered and centered cases. For the non-centered maximal operator M we prove that, given a function f: Z → R of bounded variation, =, where Var(f) represents the total variation of f. For the centered maximal operator M we prove that, given a function f: Z → R such that f ∈ ł1(Z), =. This provides a positive solution to a question of Hajłlasz and Onninen ...
