Abstract
In this paper, we obtain the reverse Bakry–Émery-type estimates for a class of hypoelliptic diffusion operator by coupling method. The (right and reverse) Poincaré inequalities and the (right and reverse) logarithmic Sobolev inequalities are presented as consequences of such estimates. Wang–Harnack inequality, Hamilton’s gradient estimate and Liouville property are also presented by the reverse logarithmic Sobolev inequality.
