AB - The aim of the paper is two-fold. First, we investigate the ψ-Bessel potential spaces on $ℝ_{0+}^{n+1}$ and study some of their properties. Secondly, we consider the fractional powers of an operator of the form
$-A_± = -ψ(D_{x^{\prime }}) ± ∂/(∂x_{n+1})$, $(x^{\prime },x_{n+1}) ∈ ℝ^{n+1}_{0+}$,
where $ψ(D_{x^{\prime }})$ is an operator with real continuous negative definite symbol ψ: ℝⁿ → ℝ. We define the domain of the operator $-(-A_±)^{α}$ and prove that with this domain it generates an $L_{p}$-sub-Markovian semigroup.
