Abstract: | In this note, we propose to remove some small gaps in the theory of potential spaces H
p
s
(Ω) and Besov spaces B
p
s
(Ω), 1 < p < ∞, s ∈ ℝ, for a bounded Lipschitz domain Ω ⊂ ℝ
n
, n ⩾ 2. Namely, we discuss 1) the unified definitions of these spaces with s of any sign, the unified duality theorems and interpolation relations, 2) the possibility of constructing a function in these
spaces with given array of traces of its derivatives on the boundary.
