Sobolev type spaces Eαs,p (α ≥ 0, s ∈ ℝ, p ∈ [1, +∞]) are defined on ℝ × ℕ by using the Fourier transform and its inverse on the Laguerre hypergroup. An analogue of Hs (ℝn), denoted by Hα s is investigated in this paper. Some properties including completeness and imbedding results for these spaces are given, Reillich-type theorem and Poincaré's inequality are proved. Also, global regularity results for certain differential operators are obtained.
