本文给出了$\mathbb{R}^n$上次临界Trudinger-Moser不等式的一个新的证明。关于这个不等式的所有现有证明都是基于Sobolev空间$W^{1,n}(\mathbb{R}^n)$中函数的重排论证。我们的方法避免了这种技术,因此可以用于黎曼流形的情况下,并在整个海森堡群。
In this note, we give a new proof of subcritical Trudinger-Moser inequality on $\mathbb{R}^n$. All the existing proofs on this inequality are based on the rearrangement argument with respect to functions in the Sobolev space $W^{1,n}(\mathbb{R}^n)$. Our method avoids this technique and thus can be used in the Riemannian manifold case and in the entire Heisenberg group.
