   <mods:abstract>In this talk, I will introduce the Sawyer's conjecture,&#xd;
which was proposed by Sawyer in 1980s. Then in 2005, Cruz-Uribe,&#xd;
Martell and Pérez finally solved this conjecture, they also proposed&#xd;
a new conjecture, which can be viewed as the most singular case of&#xd;
several extensions of Sawyer's conjecture. I will give a positive&#xd;
answer to the new conjecture. Several quantitative estimates are also&#xd;
obtained.  In the end, some open questions related to one-sided&#xd;
maximal functions (proposed by Martín Reyes) will be introduced. This&#xd;
talk is based on joint work with Sheldy Ombrosi and Carlos Pérez.</mods:abstract>
