The derivative of the fractional discrete Laplacian is an exotic Riesz potential

Bo Li, Qingze Lin, Huoxiong Wu

Let $Δ_{N}$ be the multidimensional discrete Laplacian on $Z^{N}$ ( $N \geq 1$ ). In this note, we prove that, when $N = 1$ , the right hand derivative of $(- Δ_{1})^{s}$ at $0$ is an ex…

Dirichlet problem for Schrödinger operators on Heisenberg groups

Ji Li, Qingze Lin, Liang Song

We investigate the Dirichlet problem associated to the Schrödinger operator $L = - Δ_{H^{n}} + V$ on Heisenberg group $H^{n}$ : \begin{align*} \begin{cases} \partia…
