Isoperimetric inequalities in simplicial complexes [PDF]

open access: yesCombinatorica, 2015
In graph theory there are intimate connections between the expansion properties of a graph and the spectrum of its Laplacian. In this paper we define a notion of combinatorial expansion for simplicial complexes of general dimension, and prove that similar connections exist between the combinatorial expansion of a complex, and the spectrum of the high ...

Bonnesen-style symmetric mixed inequalities

open access: yesJournal of Inequalities and Applications, 2016
In this paper, we investigate the symmetric mixed isoperimetric deficit Δ 2 ( K 0 , K 1 ) $\Delta_{2}(K_{0},K_{1})$ of domains K 0 $K_{0}$ and K 1 $K_{1}$ in the Euclidean plane R 2 $\mathbb{R}^{2}$ .

Log-Minkowski inequalities for the Lp $L_{p}$-mixed quermassintegrals

open access: yesJournal of Inequalities and Applications, 2019
Böröczky et al. proposed the log-Minkowski problem and established the plane log-Minkowski inequality for origin-symmetric convex bodies. Recently, Stancu proved the log-Minkowski inequality for mixed volumes; Wang, Xu, and Zhou gave the Lp $L_{p ...

On Isoperimetric Inequalities in Minkowski Spaces

open access: yesJournal of Inequalities and Applications, 2010
The purpose of this expository paper is to collect some (mainly recent) inequalities, conjectures, and open questions closely related to isoperimetric problems in real, finite-dimensional Banach spaces (= Minkowski spaces).

Dual Orlicz geominimal surface area

open access: yesJournal of Inequalities and Applications, 2016
The L p $L_{p}$ -geominimal surface area was introduced by Lutwak in 1996, which extended the important concept of the geominimal surface area. Recently, Wang and Qi defined the p-dual geominimal surface area, which belongs to the dual Brunn-Minkowski ...

Isoperimetric inequality and applications

open access: yes, 2021
U ovom diplomskom radu opisana je prva pojava izoperimetrijskog problema u matematici te otkriće tog problema (legenda o Didoni) i važnost u svakidašnjem životu. Rezultat izoperimetrijskog problema jest izoperimetrijska nejednakost.

Functional Geominimal Surface Area and Its Related Affine Isoperimetric Inequality

open access: yesJournal of Function Spaces, 2020
The first variation of the total mass of log-concave functions was studied by Colesanti and Fragalà, which includes the Lp mixed volume of convex bodies. Using Colesanti and Fragalà’s first variation formula, we define the geominimal surface area for log-

Exponential convergence for ultrafast diffusion equations with log‐concave weights

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 9, September 2026.
Abstract We study the asymptotic behavior of a weighted ultrafast diffusion PDE on the real line, with a log‐concave and log‐lipschitz weight, and prove exponential convergence to equilibrium. This result goes beyond the compact setting studied in Iacobelli [Discrete Contin. Dyn. Syst. 39 (2019), 4929–4943].

On the deterministic interior body of random polytopes

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 2, August 2026.
Abstract Let {Xi}i=1∞$\lbrace X_i\rbrace _{i=1}^{\infty }$ be a sequence of independent copies of a random vector X$X$ in Rn$\mathbb {R}^n$. We revisit the question to determine the asymptotic shape of the random polytope KN=conv{X1,…,XN}$K_N={\rm conv}\lbrace X_1,\ldots,X_N\rbrace$ where N>n$N>n$.
