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. WebFor a Euclidean space with a dyadic filtration, the dyadic maximal operator is the above Doob maximal operator. For the dyadic maximal operator, the constant 1 / (p − 1) is the optimal power on [v] A p (see, e.g., [3,4]). It follows that the constant 1 / (p − 1) is also the optimal power on [v] A p for the Doob maximal operator M.
