Bergman Spaces and Carleson Measures on Homogeneous Isotropic Trees

摘要

Hastings studied Carleson measures for non-negative subharmonic functions on the polydisk and characterized them by a certain geometric condition relative to Lebesgue measure sigma. Cima & Wogen and Luecking proved analogous results for weighted Bergman spaces on the unit ball and other open subsets of C-n. We consider a similar problem on a homogeneous tree, and study how the characterization and properties of Carleson measures for various function spaces depend on the choice of reference measure sigma.
