This text provides the reader with a general overview of the field, with its motivations and problems, some of its fundamental results, and some recent lines of development.SpringerBriefs in mathematics.Hypoelliptic operatorsHypoelliptic operators.515Bramanti Marcoauthttp://id.loc.gov/vocabulary/relators/aut284761MiFhGGMiFhGGBOOK9910299964203321Invitation to hypoelliptic operators and Hörmander's vector fields1410208UNINA
