The setting we consider is heterogeneous, encompassing both varying sample sizes and differential privacy constraints across servers. Within this framework, both global and pointwise estimation are considered, and optimal rates of convergence over the Besov spaces are established.\n  Distributed privacy-preserving estimators are proposed and their risk properties are investigated.
