[The Hardy–Littlewood maximal function on some metric measure spaces]
In this Note, we study the behavior of the Hardy–Littlewood maximal function M on cusp manifolds in terms of the growth of the volume of the base space. In particular, we prove that for all 1<p0<+∞ fixed, there exists such a manifold on which M is bounded on Lp for p>p0 but not for 1⩽p<p0.
Dans cette Note, on se propose d'étudier le comportement de la fonction maximale de Hardy–Littlewood, M, sur l'espace cuspidale en termes de la croissance du volume de la base. En particulier, on montre que pour tout 1<p0<+∞ fixé, il existe une variété sur laquelle l'opérateur M est borné sur Lp pour p>p0 mais pas pour 1⩽p<p0.
