Spherical functions and spectrum of the Laplacian on semi-homogeneous trees

Enrico Casadio Tarabusi, Massimo A. Picardello

On a semi-homogeneous tree, we study the $ℓ^{p}$ -spectrum of the Laplace operator $μ_{1}$ (the isotropic nearest-neighbor transition operator); the known results in the much simpler…

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…
