Abstract: In this talk we will discuss weighted endpoint estimates for
the Hardy-Littlewood maximal function on the infinite rooted $k$-ary
tree. Namely, we will show a variant of the Fefferman-Stein estimate
with respect to the weights $(w, M_{s}w)$. Moreover, it is shown it is
sharp, in the sense that it does not hold in general if $s=1$. This
result is a generalization of the unweighted case ($w\equiv1$)
independently obtained by Naor-Tao and Cowling-Meda-Setti. We will also
present more general sufficient conditions for the strong estimates in
the case $p>1$./

This talk is based on joint works with Israel Rivera-Ríos (UNS&UMA) and
Martíin Safe (UNS).
/This will be a hybrid seminar. All are very welcome to join either
online or in person. Venue: Luigi Stasi Seminar Room (ICTP Leonardo Da
Vinci Building), for those wishing to attend in person./
