On some improved weighted weak type inequalities
Andrei K. Lerner, Kangwei Li, Sheldy Ombrosi +1
In this paper we obtain the sharp quantitative matrix weighted weak type bounds for the Christ--Goldberg maximal operator in the case , improving a recent result b…

Weighted maximal inequalities on hyperbolic spaces
Jorge Antezana, Sheldy Ombrosi
In this work we develop a weight theory in the setting of hyperbolic spaces. Our starting point is a variant of the well-known endpoint Fefferman-Stein inequality for the centered…

Endpoint mixed weak type extrapolation
Sheldy Ombrosi, Israel P. Rivera-Ríos
The purpose of this note is to extend the extrapolation result by by Cruz-Uribe Martell and Pérez as follows. Given a family of pairs of functions suppose that for so…
