In this paper we prove mixed-means inequalities for integral power means of an arbitrary real order, where one of the means is taken over the ball B(x, δ|x|), centered at x ∈ R n and of radius δ|x|, δ > 0. Therefrom we deduce the corresponding Hardy-type inequality, that is, the operator norm of the operator S δ which averages |f | ∈ L p (R n ) over B(x, δ|x|), introduced by Christ and Grafakos in Proc. Amer. Math. Soc. 123 (1995) 1687-1693. We also obtain the operator norm of the related limiting geometric mean operator, that is, Carleman or Levin-Cochran-Lee-type inequality. Moreover, we indicate analogous results for annuli and discuss estimations related to the HardyLittlewood and spherical maximal functions.
