Geometric maximal operators and BMO on product bases

Functional Analysis 2020-07-29 v1

Abstract

We consider the problem of the boundedness of maximal operators on BMO on shapes in Rn\mathbb{R}^n. We prove that for bases of shapes with an engulfing property, the corresponding maximal function is bounded from BMO to BLO, generalising a known result of Bennett for the basis of cubes. When the basis of shapes does not possess an engulfing property but exhibits a product structure with respect to lower-dimensional shapes coming from bases that do possess an engulfing property, we show that the corresponding maximal function is bounded from BMO to a space we define and call rectangular BLO.
