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…
Minimal conditions for BMO
Javier Canto, Carlos Perez, Ezequiel Rela
We study minimal integrability conditions via Luxemburg-type expressions with respect to generalized oscillations that imply the membership of a given function to the space BMO…
A note on generalized Fujii-Wilson conditions and BMO spaces
Sheldy Ombrosi, Carlos Pérez, Israel P. Rivera-Ríos +1
In this note we generalize the definition of Fujii-Wilson condition providing quantitative characterizations of some interesting classes of weights, such as , $A_\infty^{…
Degenerate Poincaré-Sobolev inequalities
Carlos Pérez, Ezequiel Rela
We study weighted Poincaré and Poincaré-Sobolev type inequalities with an explicit analysis on the dependence on the constants of the involved weights. We obtain inequalities…
Vector-valued operators, optimal weighted estimates and the condition
Maria Eugenia Cejas, Kangwei Li, Carlos Perez +1
Sharp weighted estimates are obtained for vector-valued extensions of the Hardy-Littlewood maximal operator, Calderón-Zygmund operators and Coifman-Rochberg-Weiss commutator. Those…
A lower bound for exponents for some weighted weak-type inequalities
Carlos Pérez, Israel P. Rivera-Ríos
We give a weak-type counterpart of the main result in an earlier work of the first author, E. Rela and T. Luque which allows to provide a lower bound for the exponent of the $A_{p}…
