WebDec 1, 2008 · We obtain sharp estimates for the localized distribution function of the dyadic maximal function M ϕ d, given the local L 1 norms of ϕ and of G ϕ where G is a convex increasing function such that G (x) / x → + ∞ as x → + ∞. Using this we obtain sharp refined weak type estimates for the dyadic maximal operator.

WebJun 21, 2024 · 8.2 Estimates for the Dyadic Maximal Function: Intermediate Scales This section is intended to provide bounds independent of the dimension for the dyadic … It is still unknown what the smallest constants Cp,d and Cd are in the above inequalities. However, a result of Elias Stein about spherical maximal functions can be used to show that, for 1 < p < ∞, we can remove the dependence of Cp,d on the dimension, that is, Cp,d = Cp for some constant Cp > 0 only depending on p. It is unknown whether there is a weak bound that is independent of dimension. grand saline elementary school
