We give sufficient conditions on variable exponent functions p : Rn → [1,∞) for which the higher-order Riesz transforms, associated with the Ornstein–Uhlenbeck semigroup, are bounded on Lp(·) (Rn, dγ ), where γ denotes the ...

We prove that a generalized Fefferman-Phong type condition on a pair of weights uand v is sufficient for the boundedness of the commutators of potential type operators from Lp(·)_v into Lq(·)_u. We also give an improvement ...

En la presente tesis nos enfocamos en el estudio de algunos operadores integrales, en el contexto de los espacios de Lebesgue con exponente variable. Obtuvimos acotaciones estimaciones de tipo fuerte y de tipo débil para ...

We prove that a generalized Fefferman–Phong type conditions on a pair of weights u and v is sufficient for the boundedness of the potential type operator from Lv p(.) into Lu q(.). We also obtain an analogous estimates for ...

En el Análisis Armónico nos encontramos frecuentemente con el problema de la continuidad, en diferentes contextos, de una amplia gama de operadores que surgen del estudio de la regularidad de soluciones de ecuaciones ...

We characterize the weights for the Stieltjes transform and the Calder´on operator to be bounded on the weighted variable Lebesgue spaces $L_w^{p(cdot)}(0,infty)$, assuming that the exponent function $pp$ is log-H"older ...

We obtain boundedness results for the higher order commutators of singular integral operators between weighted Lebesgue spaces, including Lp-BMO and Lp-Lipschitz estimates. The kernels of such operators satisfy certain ...

En el presente trabajo estudiamos la acotación de ciertos operadores integrales sobre los espacios de Lebesgue variables. En el capítulo I, damos los preliminares necesarios, en el II, comparamos las distintas técnicas con ...

In this note we will characterize the boundedness, invertibility, compactness and closedness of the range of multiplication operators on variable Lebesgue spaces.
