Abstract:Given a centered convex body , we study the optimal value of the constant such that there exists an orthonormal basis for which the following reverse dual Loomis-Whitney inequality holds:
We prove that for some absolute and that this estimate in terms of , the isotropic constant of , is asymptotically sharp in the sense that there exist another absolute constant and a convex body such that . We also prove more general reverse dual Loomis-Whitney inequalities as well as reverse restricted versions of Loomis-Whitney and dual Loomis-Whitney inequalities.

通过各向同性逆Loomis-Whitney不等式
摘要:给定一个中心凸体,我们研究常数的最佳值,以便存在一个正交的基础,并成立以下逆对偶Loomis-Whitney不等式:
我们证明了一些绝对和这个估计来讲,的迷向常数,是在这个意义上渐近尖锐了存在另一个绝对常数和凸体这样。我们还证明了更一般的反向双重Loomis-Whitney不等式,以及反向限制性版本的Loomis-Whitney和双重Loomis-Whitney不等式。
