"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. " - Dyadic maximal function
