临界和次临界Trudinger-Moser-Adams不等式的等价性

Equivalence of critical and subcritical sharp Trudinger-Moser-Adams inequalities

Nguyen Lam, Guozhen Lu, Lu Zhang

摘要:

一阶索伯列夫空间上的SharpTrudinger-Moser不等式和高阶索伯列夫空间上类似的Adams不等式在几何分析、偏微分方程和现代数学的其他分支中起着重要的作用。近年来,这类几何不等式已被许多作者广泛研究,并有大量的文献。这类最优不等式有两种类型:临界和次临界尖锐不等式,它们都有最优常数。临界尖锐不等式是在所考虑的函数的全部Sobolev范数的限制下,而次临界不等式是在所考虑的函数的部分Sobolev范数的限制下。这两类不等式之间有细微的差别。令人惊讶的是,我们在本文中证明,这些临界和亚临界Trudinger-Moser和亚当斯不等式实际上是等价的。此外,我们还建立了整个欧几里得空间上的次临界Trudinger-Moser不等式和Adams不等式的上确界的渐近性质(定理1.1和定理1.3),并给出了临界Trudinger-Moser不等式和次临界Trudinger-Moser不等式和Adams不等式的上确界之间的精确关系(定理1.2和定理1.4)。

英文摘要:

Sharp Trudinger-Moser inequalities on the first order Sobolev spaces and their analogous Adams inequalities on high order Sobolev spaces play an important role in geometric analysis, partial differential equations and other branches of modern mathematics. Such geometric inequalities have been studied extensively by many authors in recent years and there is a vast literature. There are two types of such optimal inequalities: critical and subcritical sharp inequalities, both are with best constants. Critical sharp inequalities are under the restriction of the full Sobolev norms for the functions under consideration, while the subcritical inequalities are under the restriction of the partial Sobolev norms for the functions under consideration. There are subtle differences between these two type of inequalities. Surprisingly, we prove in this paper that these critical and subcritical Trudinger-Moser and Adams inequalities are actually equivalent. Moreover, we also establish the asymptotic behavior of the supremum for the subcritical Trudinger-Moser and Adams inequalities on the entire Euclidean spaces (Theorem 1.1 and Theorem 1.3) and provide a precise relationship between the supremums for the critical and subcritical Trudinger-Moser and Adams inequalities (Theorem 1.2 and Theorem 1.4).
