Numerical analysis of doubly-history dependent variational inequalities in contact mechanics

Fixed Point Theory and Algorithms for Sciences and Engineering, 2021
This paper is devoted to numerical analysis of doubly-history dependent variational inequalities in contact mechanics. A fully discrete method is introduced for the variational inequalities, in which the doubly-history dependent operator is approximated ...

Exponential Inequalities for Positive Linear Mappings

Journal of Function Spaces, 2018
In this article, we present exponential-type inequalities for positive linear mappings and Hilbert space operators, by means of convexity and the Mond-Pečarić method. The obtained results refine and generalize some known results.

On the Landau-Kolmogorov inequality between $\| f' \|_{\infty}$, $\| f \|_{\infty}$ and $\| f''' \|_1$

Researches in Mathematics, 2019
We solve the Landau-Kolmogorov problem on finding sharp additive inequalities that estimate $\| f' \|_{\infty}$ in terms of $\| f \|_{\infty}$ and $\| f''' \|_1$.

Operator upper bounds for Davis-Choi-Jensen's difference in Hilbert spaces [PDF]

Mathematica Moravica
In this paper we obtain several operator inequalities providing upper bounds for the Davis-Choi-Jensen's Difference Ph (f (A)) - f (Ph (A)) for any convex function f : I → R, any selfadjoint operator A in H with the spectrum Sp (A) ⊂ I and any linear ...

A note on some inequalities for positive linear maps [PDF]

, 2017
We improve and generalize some operator inequalities for positive linear maps. It is shown, among other inequalities, that if or , then for each and , and where , and . We also obtain an improvement of operator Pólya-Szegö inequality.

Weighted norm inequalities for polynomial expansions associated to some measures with mass points

, 1995
Fourier series in orthogonal polynomials with respect to a measure $\nu$ on $[-1,1]$ are studied when $\nu$ is a linear combination of a generalized Jacobi weight and finitely many Dirac deltas in $[-1,1]$.

On Some Numerical Radius Inequalities Involving Generalized Aluthge Transform

Journal of Function Spaces, 2022
Let S be any bounded linear operator defined on a complex Hilbert space H. In this paper, we present some numerical radius inequalities involving the generalized Aluthge transform to attain upper bounds for numerical radius.

Opial Type Integral Inequalities for Widder Derivatives and Linear Differential Operators

International Journal of Analysis and Applications, 2015
In this paper we establish Opial type integral inequalities for Widder derivatives and linear di_erential operator. Also, for applications we construct some related inequalities as special cases.
