In their original paper, G.H. Hardy and J.E. Littlewood explained their maximal inequality in the language of cricket averages. Given a function f defined on R , the uncentred Hardy–Littlewood maximal function Mf of f is defined as at each x in R . Here, the supremum is taken over balls B in R which contain the point x and B denotes the measure of B (in this case a multiple of the radius of the ball raised to the power n). … WebMay 7, 2024 · The Hardy–Littlewood maximal function is defined by M (f) (x)=\sup_ {B}\frac {1} { \vert B \vert } \int _ {B} \bigl\vert f (y) \bigr\vert \, {d}y, where the supremum is taken over all balls B containing x.

In mathematics, the Hardy–Littlewood maximal operator M is a significant non-linear operator used in real analysis and harmonic analysis. The operator takes a locally integrable function f : R → C and returns another function Mf. For any point x ∈ R , the function Mf returns the maximum of a set of reals, namely the set … See more This theorem of G. H. Hardy and J. E. Littlewood states that M is bounded as a sublinear operator from the L (R ) to itself for p > 1. That is, if f ∈ L (R ) then the maximal function Mf is weak L -bounded and Mf ∈ L (R ). Before stating … See more It is still unknown what the smallest constants Cp,d and Cd are in the above inequalities.
