Abstract In this survey we consider a general Hormander type operator, represented¨ as a sum of squares of vector ﬁelds plus a drift and we outline the central role of the fundamental solution in developing Potential and Regularity Theory for solu-tions of related PDEs. After recalling the Gaussian behavior at inﬁnity of the kernel,

Hormander for solutions of ∂-equations had terriﬁc applications to other domains of math-ematics. Chapter VII of [Hor66] already derives a deep existence theorem for solutions of PDE equations with constant coeﬃcients. More surprisingly, there are also striking appli-cations in number theory.
