Local lower norm estimates for dyadic maximal operators and related Bellman functions

Antonios D. Melas, Eleftherios N. Nikolidakis

We provide lower $L^q$ and weak $L^p$-bounds for the localized dyadic maximal operator on $R^n$, when the local $L^1$ and the local $L^p$ norm of the function are given. We actuall…
