Failure of stability of a maximal operator bound for perturbed Nevo-Thangavelu means

Jaehyeon Ryu, Andreas Seeger

Let $G$ be a two-step nilpotent Lie group, identified via the exponential map with the Lie-algebra $g = g_{1} \oplus g_{2}$ , where $[\mathfrak g,\mathfrak g]\…

Spherical maximal functions on two step nilpotent Lie groups

Jaehyeon Ryu, Andreas Seeger

Consider $R^{d} \times R^{m}$ with the group structure of a two-step nilpotent Lie group and natural parabolic dilations. The maximal function originally introduced by N…
