Extreme points of a ball about a measure with finite support [PDF]

open access: yes, 2016
We show that, for the space of Borel probability measures on a Borel subset of a Polish metric space, the extreme points of the Prokhorov, Monge-Wasserstein and Kantorovich metric balls about a measure whose support has at most n points, consist of ...

Multiple-Term Refinements of Young Type Inequalities

open access: yesJournal of Mathematics, 2016
Recently, a multiple-term refinement of Young’s inequality has been proved. In this paper, we show its reverse refinement. Moreover, we will present multiple-term refinements of Young’s inequality involving Kantorovich constants.

Optimal transportation, topology and uniqueness [PDF]

open access: yes, 2010
The Monge-Kantorovich transportation problem involves optimizing with respect to a given a cost function. Uniqueness is a fundamental open question about which little is known when the cost function is smooth and the landscapes containing the goods to be

Several Matrix Kantorovich-Type Inequalities

open access: yesJournal of Mathematical Analysis and Applications, 1996
Let \(A\) and \(A_j\) be \(n \times n\) positive (semi-)definite Hermitian matrices with (nonzero) eigenvalues contained in the interval \([m,M]\), where \(0 < m < M\). Let \(V\) and \(V_j\) be \(n \times r\) matrices, \(B =\) block diag \((A_1, \dots, A_k)\), \(U^* = (V^*_1, \dots, V^*_k)\). Let \(R(A)\) denote the column space of \(A\).

Grüss-Type Bounds for the Covariance of Transformed Random Variables

open access: yesJournal of Inequalities and Applications, 2010
A number of problems in Economics, Finance, Information Theory, Insurance, and generally in decision making under uncertainty rely on estimates of the covariance between (transformed) random variables, which can, for example, be losses, risks, incomes ...

Generalizations of the Kantorovich and Wielandt Inequalities with Applications to Statistics

open access: yesMathematics
By utilizing the properties of positive definite matrices, mathematical expectations, and positive linear functionals in matrix space, the Kantorovich inequality and Wielandt inequality for positive definite matrices and random variables are obtained ...

An extension of the operator Kantorovich inequality

open access: yesTbilisi Mathematical Journal, 2020
Let \(A\) be a positive invertible operator on a Hilbert space \(H\) such that \(mI\le A\le MI\) where \(I\) is the identity operator on \(H\) and \(m,M\) are positive real numbers. The celebrated Kantorovich inequality asserts that \[ \langle Ax,x\rangle \langle A^{-1}x,x\rangle \le \frac{(m+M)^2}{4mM} \] for all unit vectors \(x\in H\).

A glimpse into the differential topology and geometry of optimal transport

open access: yes, 2012
This note exposes the differential topology and geometry underlying some of the basic phenomena of optimal transportation. It surveys basic questions concerning Monge maps and Kantorovich measures: existence and regularity of the former, uniqueness of ...

Approximations of Antieigenvalue and Antieigenvalue-Type Quantities

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2012
We will extend the definition of antieigenvalue of an operator to antieigenvalue-type quantities, in the first section of this paper, in such a way that the relations between antieigenvalue-type quantities and their corresponding Kantorovich-type ...
