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).

Isoperimetric inequalities of the fourth order Neumann eigenvalues

open access: yesJournal of Inequalities and Applications, 2020
In this paper, we obtain some isoperimetric inequalities for the first ( n − 1 ) $(n-1)$ eigenvalues of the fourth order Neumann Laplacian on bounded domains in an n-dimensional Euclidean space. Our result supports strongly the conjecture of Chasman.

Weighted isoperimetric inequalities in cones and applications [PDF]

open access: yes, 2012
This paper deals with weighted isoperimetric inequalities relative to cones of $\mathbb{R}^{N}$. We study the structure of measures that admit as isoperimetric sets the intersection of a cone with balls centered at the vertex of the cone.

Isoperimetric inequalities for some nonlinear eigenvalue problems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2004
In this paper we intend to review many of the known inequalities for eigenvalues of the Laplacian in Euclidean plane. Our aim is to show that we can generalize some results for the pseudo-Laplacian.

Dilation Type Inequalities for Strongly-Convex Sets in Weighted Riemannian Manifolds

open access: yesAnalysis and Geometry in Metric Spaces, 2021
In this paper, we consider a dilation type inequality on a weighted Riemannian manifold, which is classically known as Borell’s lemma in high-dimensional convex geometry.

An Asymptotic Isoperimetric Inequality [PDF]

open access: yesGeometric And Functional Analysis, 1998
For a finite metric space \(V\) with a metric \(\rho\) and probability measure \(\mu\), let \(V^n\) be the product metric space in which the distance between \(a= (a_1,\dots, a_n)\) and \(b= (b_1,\dots, b_n)\) is \(\rho_n(a,b)= \sum_i\rho(a_i, b_i)\) and the measure \(\mu_n(a_1,\dots, a_n)= \prod_i\mu(a_i)\). For any \(d\geq 0\) the \(d\)-neighbourhood

Affine vs. Euclidean isoperimetric inequalities [PDF]

open access: yesAdvances in Mathematics, 2018
It is shown that every even, zonal measure on the Euclidean unit sphere gives rise to an isoperimetric inequality for sets of finite perimeter which directly implies the classical Euclidean isoperimetric inequality.

Dual Lp-Mixed Geominimal Surface Area and Related Inequalities

open access: yesJournal of Function Spaces, 2016
The integral formula of dual Lp-geominimal surface area is given and the concept of dual Lp-geominimal surface area is extended to dual Lp-mixed geominimal surface area. Properties for the dual Lp-mixed geominimal surface areas are established.

Isoperimetric inequalities for -Hessian equations

open access: yesAdvances in Nonlinear Analysis, 2012
We consider the homogeneous Dirichlet problem for a special -Hessian equation of sub-linear type in a -convex domain , . We study the comparison between the solution of this problem and the (radial) solution of the corresponding problem in a ball having ...

Holography, probe branes and isoperimetric inequalities

open access: yesPhysics Letters B, 2015
In many instances of holographic correspondences between a d-dimensional boundary theory and a (d+1)-dimensional bulk, a direct argument in the boundary theory implies that there must exist a simple and precise relation between the Euclidean on-shell ...
