Let B be the real unit ball in R n and f C N (B). Given a multi-index m = (m 1,., m n) of nonnegative integers with | m | = N, we set the quantity s u p x B, y E (x, r), x ≠ y (1 - | x | 2) α (1 - | y | 2) β | ∂ m f (x) - ∂ m f (y) | / | x - y | γ [ x, y ] 1 - γ, x ≠ y, where 0 ≤ γ ≤ 1 and α + β = N + 1. In terms of it, we characterize harmonic Bloch and Besov spaces on the real unit ball. This generalizes the main results of Yoneda, ...
