Tóm tắt

In this paper we establish an upper estimate and a 3G-theorem for the Green function of the Khon Laplacian $$\Delta _{{\mathbb {H}}}$$ on a domain D of the Heisenberg group $${{\mathbb {H}}^n}$$ . We also establish a generalized triangle property which allows us to introduce a new Kato class for the ball.
