Let Ω be a bounded, smooth domain in ℝ2n, n ≥ 2. The well‐known Moser‐Trudinger inequality ensures the nonlinear functional Jρ(u) is bounded from below if and only if ρ ≤ ρ2n := 22nn!(n − 1)!ω2n, where $$J_{\rho}(u) = {1 \over 2} \int_{\Omega} |(-\Delta)^{n/2} u|^2 - \rho \log \int_{\Omega} e^u \,dx$$ in ${\cal X}:=H^n(\Omega)\cap \{ u, (-\Delta)^j u \in H^1_0(\Omega), j=1,\dots, [{n-1 \over 2}] \}$, and ω2n is the area of the unit sphere ?2n − 1 in ℝ2n. In this paper, we prove the infu∈X Jρ(u) is always attained for ρ ≤ ρ2n.
