On the Reverse Dual Loomis–Whitney Inequality SpringerLink

WebTHE DUAL LOOMIS-WHITNEY INEQUALITY 3 the bound is sharp for all convex bodies K in Rn whose centroid is at the origin. In this paper we will use parts of his work stated in Lemma 4.2. In particular, if ” is a cross measure on Sn¡1, we can drop the condition in Theorem 1.1 that the underlying body has centroid at the origin, and obtain a result of … Web27 de out. de 2024 · While the Loomis–Whitney inequality gives an estimate of the Lebesgue measure of a set A from above, the present paper asks for a corresponding estimate from below. Since the case of n=1 is trivial, we assume in the following that n\ge 2. troubledays 3dm

Webof the Loomis-Whitney inequality for H1 to an incidence geometric problem in the plane that we resolvedusing themethod of polynomial partitioning. Later we learned that the … WebLoomis–Whitney inequality. A simple example of this is an alternative proof of the Loomis–Whitney inequality: ... We sketch how Loomis–Whitney follows from this: Indeed, let X be a uniformly distributed random variable with values in A and so that each point in A occurs with equal probability. Web1. Loomis-Whitney Inequality Let X be a set of unit cubes in the unit cubical lattice in Rn, and let X be its volume. Let Πj be the projection onto the x⊥ j hyperplane. The motivating question is: if Πj is small for all j, what can we say about X ? j(X) ≤ A, then X . A n n−1. Remark. The sharp constant in the . is 1. troubledays dlc
