Abstract
We consider an infinite homogeneous tree \({\mathcal {V}}\) endowed with the usual metric d defined on graphs and a weighted measure \(\mu \). The metric measure space \(({\mathcal {V}},d,\mu )\) is nondoubling and of exponential growth, hence the classical theory of Hardy and BMO spaces does not apply in this setting. We introduce a space \(BMO(\mu )\) on \(({\mathcal {V}},d,\mu )\) and investigate some of its properties. We prove in particular that \(BMO(\mu )\) can be identified with the dual of a Hardy space \(H^1(\mu )\) introduced in a previous work and we investigate the sharp maximal function related with \(BMO(\mu )\).
