Fundamental solutions and local solvability for nonsmooth Hörmander's operators

Marco Bramanti, Luca Brandolini, Maria Manfredini +1

We consider operators of the form $L={\sum }_{i=1}^n{X}_i^2+X_0$ in a bounded domain of R^p where X_0, X_1,...,X_n are nonsmooth Hörmander's vector fields of step r such that th…
