We show that the two maximal operators are essentially the same. We study their weak type and strong type boundedness. We then use the weak type bounds of the Hardy-Littlewood maximal operator as a tool to differentiate integrals on dimensions higher than 1. Finally, we then study some construction of the dyadic systems in Ren-USDifferentiation and the Maximal OperatorsThesis
