Lattice point counting in Cygan--KorÃ¡nyi balls on Heisenberg groups

Sheng-Chen Mao, Sibei Yang

Lattice point counting in gauge balls on the Heisenberg group $H^{q}$ is a non-commutative analogue of the Euclidean multidimensional sphere problem, initiated by Garg, Nevo…

Equivalent Characterizations and Their Applications of Solvability of $L^{p}$ Poisson--Robin(-Regularity) Problems on Rough Domains

Xuelian Fu, Dachun Yang, Sibei Yang

Let $n \geq 2$ , $I^c ◯ \subset R^{n}$ be a bounded one-sided chord arc domain, and $p \in (1, \infty)$ . In this article, we study the (weak) $L^{p}$ Poisson--Robin(-regularity) problem f…
