Weighted Lorentz spaces: sharp mixed $A_{p} - A_{\infty}$ estimate for maximal functions

Natalia Accomazzo, Javier Duoandikoetxea, Zoe Nieraeth +2

We prove the sharp mixed $A_{p} - A_{\infty}$ weighted estimate for the Hardy-Littlewood maximal function in the context of weighted Lorentz spaces, namely \[ \|M\|_{L^{p,q}(w)} \les…

Operator-free sparse domination

Andrei K. Lerner, Emiel Lorist, Sheldy Ombrosi

We obtain a sparse domination principle for an arbitrary family of functions $f (x, Q)$ , where $x \in R^{n}$ and $Q$ is a cube in $R^{n}$ . When applied to operators, t…
