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

In the setting of the semigroup generated by the Schrodinger operator $$L= -\Delta +V$$ with the potential V satisfying an appropriate reverse Holder condition, we consider some non-local fractional differentiation operators. We study their behaviour

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

Related to the Schrödinger operator L= - Δ + V, the behaviour on Lp of several first and second order Riesz transforms was studied by Shen (Ann Inst Fourier (Grenoble) 45(2):513–546, 1995). Under his assumptions on V, a critical radius function

This work deals with weighted inequalities of the type ∫ R d | T f ( x ) | p w ( x ) d x ≤ C ∫ R d | S f ( x ) | p w ( x ) d x , where S is some maximal operator and T is an operator that comes from the harmonic analysis associated to a critica

For the system of Laguerre functions we define a suitable BMO space from the atomic version of the Hardy space considered by Dziubanski in [7], where is the maximal operator of the heat semigroup associated to that Laguerre system. We prove boundedne

In this work we give extrapolation results on weighted Lebesgue spaces for weights associated to a family of operators. The starting point for the extrapolation can be the knowledge of boundedness on a particular Lebesgue space as well as the bounded

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
