A well known result by Rubio de Francia asserts that for every finite family of disjoint intervals {I k } in R, and p in the range 2 ≤ p < ∞, there exists Cp > 0 such that X k r k S I k f L p L p ([0,1]) (R) ≤ Cpf L p (R) , where the r k 's are the Rademacher functions. In this note we prove that, given a compact connected abelian group G with dual group Γ… (More)

We define the Hermite–Sobolev spaces naturally associated to the harmonic oscillator H = −∆ + |x| 2. Structural properties, relations with the classical Sobolev spaces, boundedness of operators and almost everywhere convergence of solutions of the Schrödinger equation are also considered.

In this paper we discuss a transference method of L p-boundedness properties for harmonic analysis operators in the Hermite setting to the corresponding operators in the Laguerre context. As a byproduct of our procedure we obtain new characterizations of certain classes of Banach spaces and Köethe spaces.
