Flag Hardy spaces and partial differential equations

Abstract

After a quick introduction to flag geometry on the Heisenberg group, we discuss the problem of identifying flag atoms, which boils down to a question in PDE. We establish a conjecture of E.M.~Stein for the flag Hardy space on the Heisenberg group. The key result on which our arguments hinge is due to Baldi, Franchi and Pansu.
