AI 中文摘要
我们改进了所有$q>2$时$\text{PW}^2$到$\text{PW}^q$嵌入范数的当前最优已知界,证明该界在$q\to\fty$时是渐近最优的,方法结合了新近确立的最优Paley-Wiener集中定理与Hardy-Littlewood-Pólya优超论证。
英文摘要
We improve the currently best known bound for the norm of the embedding of $PW^2$ into $PW^q$ for all $q>2$. We show that our bound is asymptotically optimal as $q\to \infty$. Our approach combines the recently established theorem of optimal Paley-Wiener concentration with a Hardy-Littlewood-Pólya majorization argument.
