On the continuity of the Continuous Steiner Symmetrization [PDF]
, 2022 Starting from the Brock's construction of Continuous Steiner Symmetrization of sets, the problem of modifying continuously a given domain up to obtain a ball, preserving its measure and with decreasing first eigenvalue of the Laplace operator, is considered.

Stability of the Steiner symmetrization of convex sets [PDF]
Journal of the European Mathematical Society, 2013 The isoperimetric inequality for Steiner symmetrization of any codimension is investigated and the equality cases are characterized. Moreover, a quantitative version of this inequality is proven for convex sets.

Steiner symmetric extremals in Pólya–Szegö-type inequalities [PDF]
Advances in Mathematics, 2006 The aim of the present paper is to analyse the cases of equality in Steiner symmetrization inequalities for Dirichlet-type integrals. The results of the authors yield the Steiner symmetry of PS-extremals in the class of Sobolev, and more generally, BV functions, for a large class of functionals.

On Isoperimetric Inequalities in Minkowski Spaces
Journal 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).

Managerial Myopia, Earnings Guidance, and Investment*
Contemporary Accounting Research, Volume 40, Issue 1, Page 166-195, Spring 2023., 2023 ABSTRACT This study investigates the real effects of management communication, specifically of forecasts or earnings guidance, on investment. Managers can signal the strength of their projects through accuracy in their earnings guidance. This leads less accurate managers to distort their investments; the equilibrium investment strategy involves over ...

The Non-Convergence of Steiner Symmetrizations
Wuhan University Journal of Natural Sciences, 2023 In this paper, we demonstrate the existence of iterated Steiner symmetrizations of [see formula in PDF] that does not converge, even if the sequence of directions is dense in the unit sphere.

Discrete isoperimetric problems in spaces of constant curvature
Mathematika, Volume 69, Issue 1, Page 33-50, January 2023., 2023 Abstract The aim of this paper is to prove isoperimetric inequalities for simplices and polytopes with d+2$d+2$ vertices in Euclidean, spherical and hyperbolic d‐space. In particular, we find the minimal volume d‐dimensional hyperbolic simplices and spherical tetrahedra of a given inradius.

Steiner symmetrals and their distance from a ball [PDF]
Israel Journal of Mathematics, 2003 For \(\varepsilon> 0\), let \(N(n,\varepsilon)\) be the minimum number of successive Steiner symmetrizations sufficient to transform any convex body in \(\mathbb{R}^n\), with volume equal to the volume of the unit ball \(B^n\), into a convex body whose Hausdorff distance from \(B^n\) is at most \(\varepsilon\).
