A new class of hyperbolic variational–hemivariational inequalities driven by non-linear evolution equations

European journal of applied mathematics, 2020
The aim of the paper is to introduce and investigate a dynamical system which consists of a variational–hemivariational inequality of hyperbolic type combined with a non-linear evolution equation.

New Refinement of the Operator Kantorovich Inequality

Mathematics, 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.

A Generalized Viscosity Inertial Projection and Contraction Method for Pseudomonotone Variational Inequality and Fixed Point Problems

Mathematics, 2020
We introduce a new projection and contraction method with inertial and self-adaptive techniques for solving variational inequalities and split common fixed point problems in real Hilbert spaces.

PIETOOLS: A Matlab Toolbox for Manipulation and Optimization of Partial Integral Operators

, 2020
In this paper, we present PIETOOLS, a MATLAB toolbox for the construction and handling of Partial Integral (PI) operators. The toolbox introduces a new class of MATLAB object, opvar, for which standard MATLAB matrix operation syntax (e.g.

Incremental closure for systems of two variables per inequality [PDF]

, 2018
Subclasses of linear inequalities where each inequality has at most two vari- ables are popular in abstract interpretation and model checking, because they strike a balance between what can be described and what can be efficiently computed.

New inequalities for interpolational operator means [PDF]

Journal of Mathematical Inequalities, 2018
Using the properties of geometric mean, we shall show for any $0\le \alpha ,\beta \le 1$, \[f\left( A{{\nabla }_{\alpha }}B \right)\le f\left( \left( A{{\nabla }_{\alpha }}B \right){{\nabla }_{\beta }}A \right){{\sharp}_{\alpha }}f\left( \left( A{{\nabla

On weighted means and their inequalities

Journal of Inequalities and Applications, 2021
In (Pal et al. in Linear Multilinear Algebra 64(12):2463–2473, 2016), Pal et al. introduced some weighted means and gave some related inequalities by using an approach for operator monotone functions.

Hilbert-Schmidt numerical radius inequalities for operator matrices

Linear Algebra and its Applications, 2019
We prove several Hilbert-Schmidt numerical radius inequalities for operator matrices. A refinement of the triangle inequality for the Hilbert-Schmidt norm is also given.
