Variation operators on in the Schrödinger setting
J. J. Betancor, J. C. Fariña, E. Harboure +1
In this paper we prove that the variation operators associated with the heat semigroup and Riesz transforms related to the Schrödinger operator are bounded on the suitable ty…
-boundeness properties of variation operators in the Schrodinger setting
J. J. Betancor, J. C. Fariña, E. Harboure +1
In this paper we establish the -boundedness properties of the variation operators associated with the heat semigroup, Riesz transforms and commutator between Riesz transforms…
A T1 criterion for Hermite-Calderon-Zygmund operators on the BMO_H(R^n) space and applications
J. J. Betancor, R. Crescimbeni, J. C. Fariña +2
In this paper we establish a T1 criterion for the boundedness of Hermite-Calderon-Zygmund operators on the BMO_H(R^n) space naturally associated to the Hermite operator H. We apply…
Higher order Riesz transforms in the ultraspherical setting as principal value integral operators
Jorge J. Betancor, Juan C. Fariña, Lourdes Rodríguez-Mesa +1
In this paper we represent the -th Riesz transform in the ultraspherical setting as a principal value integral operator for every . We also measure the speed of…
