摘要
设为上凸且1次齐次的,其极函数表示上的Finsler度量,为中任意有界开集。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泛函在各向异性Dirichlet范数约束下的最优集中水平,其中表示有界域上各向异性Trudinger-Moser不等式的尖锐常数,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
