by Luca Brandolini and Marco Bramanti

H rmander operators are a class of linear second order partial differential operators with nonnegative characteristic form and smooth coefficients, which are usually degenerate elliptic-parabolic, but nevertheless hypoelliptic, that is highly regularizing. The study of these operators began with the 1967 fundamental paper by Lars H rmander and is intimately connected to the geometry of vector fields.Motivations for the study of H rmander operators...
