We prove an extension of Hoermander's classical result on hypoelliptic secondorder equations, where the coefficients of the related vector fields areglobally Lipschitz and satisfy the classical Hoermander condition on a denseset while the density still exists in a classical sense. Furthermore,Hoermander's classical result and related density estimates based on Malliavincalculus are recovered from an analytical point of view.
