Polyharmonic potential theory on the Poincaré disk

Massimo A. Picardello, Maura Salvatori, Wolfgang Woess

We consider the open unit disk $D$ equipped with the hyperbolic metric and the associated hyperbolic Laplacian $L$ . For $λ \in C$ and $n \in N$ …

Universal properties of the isotropic Laplace operator on homogeneous trees

Joel M. Cohen, Mauro Pagliacci, Massimo A Picardello

Let $P$ be the isotropic nearest neighbor transition operator on a homogeneous tree. We consider the $λ$ -eigenfunctions of $P$ for $λ$ outside its $ℓ^{2}$ spectrum, i.e., the eige…

Radon transforms on homogeneous trees

Enrico Casadio Tarabusi, Simon G. Gindikin, Massimo A. Picardello

We study the different horospherical Radon transforms that arise by regarding a homogeneous tree T as a simplicial complex whose simplices are vertices V, edges E or flags F (flags…
