摘要

本文关注如下nn-Laplacian平均场方程 \left\{ {\begin{array}{*{20}{c}} { - \Delta_n u = \lambda e^u} & {\rm in} \ \ \Omega, \\ {\ \ \ \ u = 0} &\ {\rm on}\ \partial\Omega, \end{array}} \right. 其中Ω\OmegaRn (n2)\mathbb{R}^n \ (n\geq 2)的光滑有界域,Δnu=div(un2u)- \Delta_n u =-{\rm div}(|\nabla u|^{n-2}\nabla u)。我们首先建立了上述nn-Laplacian平均场方程解的量子化性质。作为应用,结合Pohozaev恒等式和容量估计,我们得到了nn维单位球Bn:=Bn(0,1)B^n:=B^n(0,1)中Moser-Onofri不等式的尖锐常数C(n)C(n)infuW01,n(Bn)1nCnBnundxlnBneudxC(n),\mathop {\inf }\limits_{u \in W_0^{1,n}(B^n)}\frac{1}{ n C_n}\int_{B^n} | \nabla u|^n dx- \ln \int_{B^n} {e^u} dx\geq C(n), 这扩展了Caglioti-Lions-Marchioro-Pulvirenti在文献中的结果到nn维球的情形。这里Cn=(n2n1)n1ωn1C_n=(\frac{n^2}{n-1})^{n-1} \omega_{n-1}ωn1\omega_{n-1}BnB^n的表面积测度。对于Rn\mathbb{R}^n中一般有界域上的Moser-Onofri不等式,我们应用nn-调和移植技术给出了Moser-Onofri不等式的最优集中水平,并得到了Moser-Onofri不等式极值存在与不存在的判据。
