Several Matrix Euclidean Norm Inequalities Involving Kantorovich Inequality

open access: yesJournal of Inequalities and Applications, 2009
Kantorovich inequality is a very useful tool to study the inefficiency of the ordinary least-squares estimate with one regressor. When regressors are more than one statisticians have to extend it.

Refinements of Kantorovich Inequality for Hermitian Matrices [PDF]

open access: yesJournal of Applied Mathematics, 2012
Some new Kantorovich-type inequalities for Hermitian matrix are proposed in this paper. We consider what happens to these inequalities when the positive definite matrix is allowed to be invertible and provides refinements of the classical results.

A Note on Kantorovich Inequality for Hermite Matrices [PDF]

open access: yesJournal of Inequalities and Applications, 2011
A new Kantorovich type inequality for Hermite matrices is proposed in this paper. It holds for the invertible Hermite matrices and provides refinements of the classical results. Elementary methods suffice to prove the inequality.

Sobolev-Kantorovich Inequalities

open access: yesAnalysis and Geometry in Metric Spaces, 2015
In a recent work, E. Cinti and F. Otto established some new interpolation inequalities in the study of pattern formation, bounding the Lr(μ)-norm of a probability density with respect to the reference measure μ by its Sobolev norm and the Kantorovich ...

New Refinement of the Operator Kantorovich Inequality [PDF]

open access: yesMathematics, 2019
We focus on the improvement of operator Kantorovich type inequalities. Among the consequences, we improve the main result of the paper [H.R. Moradi, I.H. Gümüş, Z.

On the Kantorovich Inequality [PDF]

open access: yesProceedings of the American Mathematical Society, 1960
by the generalized Schwarz inequality [2, p. 262]. Now (2) follows immediately from (1) and (3), using (U*y, U*y) = (y, y). If aC is finite dimensional, the bound is attained for x U*y =u-+v, where u and v are unit eigenvectors of A corresponding to eigenvalues m and M. In the general case, the bound need not be attained; but a sequence xn= U*yn=un+vn,

Generalization on Kantorovich inequality [PDF]

open access: yesJournal of Mathematical Inequalities, 2013
In this paper, we provide a new form of upper bound for the converse of Jensen's inequality. Thereby, known estimations of the difference and ratio in Jensen's inequality are es- sentially improved. As an application, we also obtain an improvement of Kantorovich inequality.

A Baskakov-Kantorovich operators reproducing affine functions: inverse results

open access: yesJournal of Numerical Analysis and Approximation Theory, 2022
In a previous paper the author presented a Kantorovich modification of Baskakov operators which reproduce affine functions and he provided an upper estimate for the rate of convergence in polynomial weighted spaces.

On a Kantorovich-Rubinstein inequality [PDF]

open access: yesJournal of Mathematical Analysis and Applications, 2021
An easy consequence of Kantorovich-Rubinstein duality is the following: if $f:[0,1]^d \rightarrow \infty$ is Lipschitz and $\left\{x_1, \dots, x_N \right\} \subset [0,1]^d$, then $$ \left| \int_{[0,1]^d} f(x) dx - \frac{1}{N} \sum_{k=1}^{N}{f(x_k)} \right| \leq \left\| \nabla f \right\|_{L^{\infty}} \cdot W_1\left( \frac{1}{N} \sum_{k=1}^{N}{ _{x_k}} ,
