The Loomis-Whitney inequality, and the more general Uniform Cover inequality, bound the volume of a body in terms of a product of the volumes of lower-dimensional projections of the body. In this paper, we prove stability versions of these inequalities, showing that when they are close to being tight, the body in question is close in symmetric difference to a 'box'. Our results are best possible up to a constant factor depending upon the dimension alone. Our approach is information theoretic…
Measure concentration and the weak Pinsker property
It is proved that μ may be represented as a mixture of other measures in which most of the weight in the mixture is on measures that exhibit a strong kind of concentration, and the number of summands is bounded in terms of the difference between the Shannon entropy of μ$\mu$ and the combined Shannon entropies of its marginals.

It is proved that the closed convex hull $\overline{\conv}(\psi_n)$ is equal to the cone given by the uniform cover inequalities, however, perhaps surprisingly, it is shown that $\conv (\psi-n)$ is not closed for $n\ge 4$, thus disproving the conjecture.
A sharp Freiman type estimate for semisums in two and three dimensional Euclidean spaces
• Mathematics

Freiman's Theorem is a classical result in additive combinatorics concerning the approximate structure of sets of integers that contain a high proportion of their internal sums. As a consequence, one
On the nonlinear Brascamp–Lieb inequality

We prove a nonlinear variant of the general Brascamp-Lieb inequality. Instances of this inequality are quite prevalent in analysis, and we illustrate this with substantial applications in harmonic
Higher order transversality in harmonic analysis

In differential topology two smooth submanifolds S1 and S2 of euclidean space are said to be transverse if the tangent spaces at each common point together form a spanning set. The purpose of this

Measures of correlation and mixtures of product measures
The first part of this paper sets up the theory of TC and DTC for general random variables, not necessarily finite-valued, and considers the structural implications when a joint distribution $\mu$ has small TC or DTC.
Multi-variate correlation and mixtures of product measures
The first part of this paper sets up the theory of TC and DTC for general random variables, not necessarily finite-valued, and considers the structural implications when a joint distribution $\mu$ has small TC or DTC.

Some structural results are proved, bounds are given on the supremum of all δ, and the problem of actually computing the LW-constant of a rational polytope is dealt with.
Network nonlocality via rigidity of token counting and color matching
• Computer Science
Physical Review A
• 2022
This paper introduces two families of strategies to produce nonlocal correlations in networks and shows that TC and CM distributions are rigidity in wide classes of networks, meaning that there is essentially a unique classical strategy to simulate such correlations.

On the measure of intersecting families, uniqueness and stability
It is proved, for a certain range of parameters, that the t-intersecting families of maximal measure are the families of all sets containing t fixed elements, and that the extremal examples are not only unique, but also stable.

We prove that Boolean functions on Sn whose Fourier transform is highly concentrated on the first two irreducible representations of Sn, are close to being unions of cosets of point-stabilizers. We

The marriage of analytic power to geometric intuition drives many of today's mathematical advances, yet books that build the connection from an elementary level remain scarce. This engaging
Hypergraphs, Entropy, and Inequalities
The author considers a simple " triangle inequality " that the reader will later associate with a very simple (hyper)graph—namely, the triangle K 3.
Projections of Bodies and Hereditary Properties of Hypergraphs

We prove that for every M-dimensional body K, there is a rectangular parallelepiped B of the same volume as K, such that the projection of B onto any coordinate subspace is at most as large as that

The result is apparently the first example of an isoperimetric inequality for which the extremal sets do not form a nested family and there are at leastkn−1 edges between a subset of [k]n of given cardinality and its complement.

We introduce a new variational method for the study of isoperimetric inequalities with quantitative terms. The method is general as it relies on a penalization technique combined with the regularity
