Abstract Let (X n, g+)(n≥ 3) be a Poincaré–Einstein manifold which is C 3, α conformally compact with conformal infinity (∂ X,[g ˆ]). On the conformal compactification (X‾, g¯= ρ 2 g+) via a boundary defining function ρ, there are two types of Yamabe constants: Y (X‾,∂ X,[g¯]) and Q (X‾,∂ X,[g¯]).(See definitions (1) and (2).) In [13], Gursky and Han obtained an inequality between Y (X‾,∂ X,[g¯]) and Y (∂ X,[g ˆ]). In this paper, we first show that the equality holds in Gursky–Han's inequality if and only if (X n, g+) is isometric to the standard hyperbolic space (H n, g H). Secondly, we derive a conformal invariant inequality between Q (X‾,∂ X,[g¯]) and Y (∂ X,[g ˆ]), and show the equality holds if and only if (X n, g+) is isometric to (H n, g H). Based on this, we give a simple proof of the rigidity theorem for Poincaré–Einstein manifolds with conformal infinity being conformally equivalent to the standard sphere.
