Riesz transforms for the Dunkl Ornstein-Uhlenbeck operator

Adam Nowak, Luz Roncal, Krzysztof Stempak (2010)

Colloquium Mathematicae

Similarity:

We propose a definition of Riesz transforms associated to the Ornstein-Uhlenbeck operator based on the Dunkl Laplacian. In the case related to the group ℤ ₂ it is proved that the Riesz transform is bounded on the corresponding L p spaces, 1 < p < ∞.

Riesz spaces of order bounded disjointness preserving operators

Commentationes Mathematicae Universitatis Carolinae

Similarity:

Let L , M be Archimedean Riesz spaces and b ( L , M ) be the ordered vector space of all order bounded operators from L into M . We define a Lamperti Riesz subspace of b ( L , M ) to be an ordered vector subspace of b ( L , M ) such that the elements of preserve disjointness and any pair of operators in has a supremum in b ( L , M ) that belongs to . It turns out that the lattice operations in any Lamperti Riesz subspace of b ( L , M ) are given pointwise, which leads to a generalization of the classic Radon-Nikod’ym theorem...

On Limiting Case of the Stein-Weiss Type Inequality for the B-Riesz Potentials

Guliyev, Emin (2009)

Similarity:

Mathematics Subject Classification: Primary 42B20, 42B25, 42B35 In this paper we study the Riesz potentials (B-Riesz potentials) generated by the Laplace-Bessel differential operator ∆B [...]. We establish an inequality of Stein-Weiss type for the B-Riesz potentials in the limiting case, and obtain the boundedness of the B-Riesz potential operator from the space Lp,|x|β,γ to BMO|x|−λ,γ. * Emin Guliyev’s research partially supported by the grant of INTAS YS Collaborative...
