A Predictor-Corrector Methods for Mixed Inverse Variational Inequalities [PDF]

open access: yes, 2009
In this paper, a class of mixed inverse variational inequalities is introduced and studied. We prove the existence of the solution of the auxiliary problem for mixed inverse variational inequalities, suggest a predictor-corrector method for solving the ...

New Inequalities of the Kantorovich Type for Bounded Linear Operators in Hilbert Spaces [PDF]

open access: yes, 2006
Some new inequalities of the Kantorovich type are established. They hold for larger classes of operators and subsets of complex numbers than considered before in the literature and provide refinements of the classical results in the case when the ...

Time-Scale Integral Inequalities of Copson with Steklov Operator in High Dimension

open access: yesJournal of Mathematics, 2022
The paper derives some new time-scale (TS) dynamic inequalities for multiple integrals. The obtained inequalities are special cases of Copson integral using Steklov operator in (TS) version with high dimension.

Generalized k-Fractional Integral Operators Associated with Pólya-Szegö and Chebyshev Types Inequalities

open access: yesFractal and Fractional, 2022
Inequalities related to derivatives and integrals are generalized and extended via fractional order integral and derivative operators. The present paper aims to define an operator containing Mittag-Leffler function in its kernel that leads to deduce many

Operator iteration on the Young inequality

open access: yesJournal of Inequalities and Applications, 2016
In this paper, we employ iteration on operator version of the famous Young inequality and obtain more arithmetic-geometric mean inequalities and the reverse versions for positive operators.

Several inequalities for an integral transform of positive operators in Hilbert spaces with applications

open access: yesCubo, 2023
For a continuous and positive function $w\left( \lambda \right) ,$ $\lambda >0$ and $\mu $ a positive measure on $(0,\infty )$ we consider the following integral transform % \begin{equation*} \mathcal{D}\left( w,\mu \right) \left( T\right) :=\int_{0}^{
