Restricted weak type endpoint estimate for the spherical maximal operators on the Heisenberg group

Hyunwoo Jeon, Joonil Kim

Let ${\mathbb{H}}^n$ denote the Heisenberg group, identified with ${\mathbb{R}}^d\times \mathbb{R}$, where $d=2n$ and $n\in \mathbb{N}$. We consider the spherical maximal operator…
