Weighted Lorentz spaces: sharp mixed estimate for maximal functions
Natalia Accomazzo, Javier Duoandikoetxea, Zoe Nieraeth +2
We prove the sharp mixed weighted estimate for the Hardy-Littlewood maximal function in the context of weighted Lorentz spaces, namely \[ \|M\|_{L^{p,q}(w)} \les…
Singular and fractional integral operators on weighted local Morrey spaces
Javier Duoandikoetxea, Marcel Rosenthal
We obtain a characterization of the weighted inequalities for the Riesz transforms on weighted local Morrey spaces. The condition is sufficient for the boundedness on the same spac…
Muckenhoupt-type conditions on weighted Morrey spaces
Javier Duoandikoetxea, Marcel Rosenthal
We define a Muckenhoup-type condition on weighted Morrey spaces using the Köthe dual of the space. We show that the condition is necessary and sufficient for the boundedness of the…
Boundedness properties in a family of weighted Morrey spaces with emphasis on power weights
Javier Duoandikoetxea, Marcel Rosenthal
We define a scale of weighted Morrey spaces which contains different weighted versions appearing in the literature. This allows us to obtain weighted estimates for operators in a u…
Boundedness of operators on certain power-weighted Morrey spaces beyond the Muckenhoupt weights
Javier Duoandikoetxea, Marcel Rosenthal
We prove that for operators satistying weighted inequalities with weights the boundedness on a certain class of Morrey spaces holds with weights of the form for $…
Extension and boundedness of operators on Morrey spaces from extrapolation techniques and embeddings
Javier Duoandikoetxea, Marcel Rosenthal
We prove that operators satisfying the hypotheses of the extrapolation theorem for Muckenhoupt weights are bounded on weighted Morrey spaces. As a consequence, we obtain at once a…
Self-adjoint extensions of Dirac operators with Coulomb type singularity
Naiara Arrizabalaga, Javier Duoandikoetxea, Luis Vega
In this work we construct self-adjoint extensions of the Dirac operator associated to Hermitian matrix potentials with Coulomb decay and prove that the domain is maximal. The resul…
