In this work we search for boundedness results for operators related to the semigroup generated by the degenerate Schrodinger operator ${{\mathscr{L}}} u = -\frac {1}{\omega } \text {div} A\cdot \nabla u +V u$ , where ω is a weight, A is a matrix de

We introduce classes of pairs of weights closely related to Schrödinger operators, which allow us to get two-weight boundedness results for the Schrödinger fractional integral and its commutators. The techniques applied in the proofs strongly rely

In this article we prove that the fractional integral operator associated to the Schrödinger second order differential operator L-α/2=(-Δ + V)-α/2maps with continuity weak Lebesgue space Lp,∞(v) into weighted Campanato-Hölder type spaces BMOβ

For a proper open set $Omega$ immersed in a metric space with the weak homogeneity property, and given a measure $mu$ doubling on a certain family of balls lying ``well inside´´ of $Omega$, we introduce local operators of singular and fractional ty

In this work we obtain weighted and weak estimates for the commutator of the Riesz transforms associated to a Schrödinger operator , where V satisfies some reverse-Hölder inequality. The classes of weights as well as the classes of symbols are larg

In this paper we characterize the weighted BMO ( ω ) ( X ) , with X a space of homogeneous type, through an adequate weighted Carleson measure. As a byproduct we can define the weighted Triebel–Lizorkin space F ˙ ∞ 0 , 2 ( ω ) ( X ) and obtain

For a local maximal function defined on a certain family of cubes lying “well inside” of Ω , a proper open subset of Rn, we characterize the couple of weights (u, v) for which it is bounded from Lp(v) on Lq(u). Fil: Salinas, Oscar Mario. Consejo

We study weighted modular inequalities for a generalized maximal operator associated to a Young function in the context of spaces of homogeneous type. We prove the equivalence between these inequalities and a Dini-type condition, which involves the f
