In this talk, I will first introduce an inequality for the Yamabe constants of order 1 and of order 2.  By characterizing the equality case, this leads to a rigidity theorem for the conformally compact Einstein manifold. Then I will introduce my recent work on the inequalities (pointwise) for the fractional Q-curvatures of different orders, as well as some interesting applications of these inequalities.
