摘要

FFRn\mathbb{R}^{n}上凸且1次齐次的,其极函数FoF^{o}表示Rn\mathbb{R}^{n}上的Finsler度量,Ω\OmegaRn\mathbb{R}^{n}中任意有界开集。本文首先构建各向异性调和移植的理论结构。利用各向异性调和移植、余面积公式、极限Sobolev逼近法、Green函数水平集的精细估计,我们研究了Trudinger-Moser泛函Ωeλnunn1dx \int_{\Omega}e^{\lambda_{n}|u|^{\frac{n}{n-1}}}dx 在各向异性Dirichlet范数约束ΩFn(u)dx1\int_{\Omega}F^{n}\left( \nabla{{u}}\right) dx\leq1下的最优集中水平,其中λn=nnn1κn1n1 \lambda_{n}=n^{\frac{n}{n-1}}\kappa _{n}^{\frac{1}{n-1}}\ 表示有界域上各向异性Trudinger-Moser不等式的尖锐常数,κn\kappa_{n}为单位Wulff球的Lebesgue测度。作为应用,我们可立即推得有界域上各向异性Trudinger-Moser不等式极值元的存在性。最后,我们还考虑了各向异性奇异Trudinger-Moser泛函的最优集中水平。该方法基于极限Hardy-Sobolev逼近法及构造合适的归一化各向异性集中序列。

When using the polynomial approximation functional to prove the optimal concentration upper bound of the Trudinger-Moser inequality, we can not show that the order of limits can be exchanged
