The classical Calderón-Zygmund theory was developed in the Euclidean
space and, more generally, on spaces of homogeneous type, which are measure
metric spaces with the doubling property.
In this talk we consider trees endowed with flow measures, which are nondoubling
measures of at least exponential growth. In this setting, we develop
a Calderón-Zygmund theory and we define BMO and Hardy spaces, proving
a number of desired results extending the corresponding theory as known in
the classical setting.
This is a joint work with Matteo Levi, Federico Santagati and Anita Tabacco.
