Per un operatore non variazionale strutturato su campi di Hörmander con
drift, con matrice dei coecienti reale, simmetrica e uniformemente denita positiva, proviamo stime a priori locali sulle derivate seconde rispetto ai campi, in spazi di Hölder se i coecienti sono Holderiani, in spazi Lp se i coecienti sono misurabili, limitati e localmente VMO.
