| Abstract: |
| We discuss Hardy-Littlewood-Sobolev inequalities and nonlocal isoperimetric inequalities adapted to hypoelliptic operators of Kolmogorov type. We focus on the role played by the non-symmetric semigroup and by the the growth for large scales of the volume of the intrinsic pseudoballs. The talk is based on a joint project with N. Garofalo. |
