Positive Eigenfunctions of the Laplacian and Conformal Densities on Homogeneous Trees
Michel Coornaert, Athanase Papadopoulos · Journal of the London Mathematical Society · 1997
In this paper, we study some asymptotic aspects of the positive eigenfunctions of the combinatorial Laplacian associated to a homogeneous tree. The results are inspired by results of Dennis Sullivan concerning λ-harmonic functions on the hyperbolic spaces Hn and contained in the paper [9].
