  bibo_abstract:
  - In this paper we study a variant of the uncentred Hardy--Littlewood maximal operator
    on Damek--Ricci spaces in which balls are replaced by suitable half balls. Perhaps
    surprisingly, such modified maximal operator has better boundedness properties
    than the classical one. In particular, it satisfies an $L\log L$ endpoint estimate
    and it is bounded on $L^p$ for every $p$ in $(1,\infty]$.@eng
