Weighted Brunn-Minkowski theory I: On weighted surface area measures

M Fradelizi, D Langharst, M Madiman… - Journal of Mathematical …, 2024 - Elsevier
Abstract The Brunn-Minkowski theory in convex geometry concerns, among other things, the
volumes, mixed volumes, and surface area measures of convex bodies. We study …

Weighted Minkowski's existence theorem and projection bodies

L Kryvonos, D Langharst - Transactions of the American Mathematical …, 2023 - ams.org
The Brunn-Minkowski Theory has seen several generalizations over the past century. Many
of the core ideas have been generalized to measures. With the goal of framing these …

Affine fractional Sobolev and isoperimetric inequalities

J Haddad, M Ludwig - arXiv preprint arXiv:2207.06375, 2022 - arxiv.org
Sharp affine fractional Sobolev inequalities for functions on $\mathbb R^ n $ are
established. For each $0< s< 1$, the new inequalities are significantly stronger than (and …

Affine isoperimetric inequalities for higher-order projection and centroid bodies

J Haddad, D Langharst, E Putterman… - arXiv preprint arXiv …, 2023 - arxiv.org
In 1970, Schneider generalized the difference body of a convex body to higher-order, and
also established the higher-order analogue of the Rogers-Shephard inequality. In this …

Generalizations of Berwald's Inequality to Measures

D Langharst, E Putterman - arXiv preprint arXiv:2210.04438, 2022 - arxiv.org
The inequality of Berwald is a reverse-H\" older like inequality for the $ p $ th average, $ p\in
(-1,\infty), $ of a non-negative, concave function over a convex body in $\mathbb {R}^ n …

Existence of solution for -Minkowski problem of with measures in

C Li, G Wei - International Journal of Mathematics, 2023 - World Scientific
In 2019, Livshyts studied the Minkowski problem of measures in ℝ n with positive
homogeneous and positive concave density functions. After that, Wu studied the L p …

The John ellipsoids for general measures

W Ai, Q Huang - Geometriae Dedicata, 2023 - Springer
The L p John ellipsoids for general measures are proposed, which aims to extend the L p
John ellipsoids introduced by Lutwak, Yang, Zhang in their most possible general settings …

On higher-order extensions of the weighted projection body operator

D Langharst, E Putterman, M Roysdon, D Ye - arXiv preprint arXiv …, 2023 - arxiv.org
For a convex body $ K $ in $\mathbb {R}^ n $, the inequalities of Rogers-Shephard and
Zhang, written succinctly, are $\text {vol} _n (DK)\leq\binom {2n}{n}\text {vol} _n (K)\leq\text …

Fixed points of mean section operators

L Brauner, O Ortega-Moreno - arXiv preprint arXiv:2302.11973, 2023 - arxiv.org
We characterize rotation equivariant bounded linear operators from $ C (\mathbb {S}^{n-1})
$ to $ C^ 2 (\mathbb {S}^{n-1}) $ by the mass distribution of the spherical Laplacian of their …

D LANGHARST, ELI PUTTERMAN - arXiv preprint arXiv …, 2022 - researchgate.net
The inequality of Berwald is a reverse-Hölder like inequality for the pth average, p∈(− 1,∞),
of a non-negative, concave function over a convex body in Rn. We prove Berwald's …
