We prove various extensions of the Loomis–Whitney inequality and its dual, where the subspaces on which the projections (or sections) are considered are either spanned by vectors w i of a not necessarily orthonormal basis of R n , or their orthogonal complements. In order to prove such inequalities, we estimate the constant in the Brascamp–Lieb inequality in terms of the vectors w i . Restricted and functional versions of the inequality will also be considered.

关于仿射不变量和局部 Loomis-Whitney 型不等式

我们证明了 Loomis-Whitney 不等式及其对偶的各种扩展,其中考虑投影(或部分)的子空间要么由向量跨越 一世 不一定是正交基 电阻 n ,或它们的正交补。为了证明这种不等式,我们根据向量估计 Brascamp-Lieb 不等式中的常数 一世 . 不等式的受限版本和函数版本也将被考虑。
