Optimal concentration of information content for log-concave densities

M Fradelizi, M Madiman, L Wang - High Dimensional Probability VII: The …, 2016 - Springer
An elementary proof is provided of sharp bounds for the varentropy of random vectors with
log-concave densities, as well as for deviations of the information content from its mean …

The Entropic Barrier Is n-Self-Concordant

S Chewi - Geometric Aspects of Functional Analysis: Israel …, 2023 - Springer
For any convex body K⊆ ℝ n, S. Bubeck and R. Eldan introduced the entropic barrier on K
and showed that it is a (1+ o (1)) n-self-concordant barrier. In this note, we observe that the …

Beyond traditional curvature-dimension I: new model spaces for isoperimetric and concentration inequalities in negative dimension

E Milman - Transactions of the American Mathematical Society, 2017 - ams.org
We study the isoperimetric, functional and concentration properties of $ n $-dimensional
weighted Riemannian manifolds satisfying the Curvature-Dimension condition, when the …

Brascamp–Lieb-type inequalities on weighted Riemannian manifolds with boundary

AV Kolesnikov, E Milman - The Journal of Geometric Analysis, 2017 - Springer
It is known that by dualizing the Bochner–Lichnerowicz–Weitzenböck formula, one obtains
Poincaré-type inequalities on Riemannian manifolds equipped with a density, which satisfy …

[HTML][HTML] Spectral gap for spherically symmetric log-concave probability measures, and beyond

M Bonnefont, A Joulin, Y Ma - Journal of Functional Analysis, 2016 - Elsevier
Let μ be a probability measure on R n (n≥ 2) with Lebesgue density proportional to e− V (‖
x‖), where V: R+→ R is a smooth convex potential. We show that the associated spectral …

Dimensional improvements of the logarithmic Sobolev, Talagrand and Brascamp–Lieb inequalities

F Bolley, I Gentil, A Guillin - The Annals of Probability, 2018 - JSTOR
In this work, we consider dimensional improvements of the logarithmic Sobolev, Talagrand
and Brascamp–Lieb inequalities. For this, we use optimal transport methods and the Borell …

A family of Beckner inequalities under various curvature-dimension conditions

I Gentil, S Zugmeyer - 2021 - projecteuclid.org
In this paper, we offer a proof for a family of functional inequalities interpolating between the
Poincaré and the logarithmic Sobolev (standard and weighted) inequalities. The proofs rely …

Concentration of information content for convex measures

M Fradelizi, J Li, M Madiman - 2020 - projecteuclid.org
We establish sharp exponential deviation estimates of the information content as well as a
sharp bound on the varentropy for the class of convex measures on Euclidean spaces. This …

Threshold for the expected measure of random polytopes

S Brazitikos, A Giannopoulos, M Pafis - Mathematische Annalen, 2024 - Springer
Let μ be a log-concave probability measure on R n and for any N> n consider the random
polytope KN= conv {X 1,…, XN}, where X 1, X 2,… are independent random points in R n …
