On wavelets Kantorovich ( p , q ) $(p,q)$ -Baskakov operators and approximation properties
Journal of Inequalities and Applications, 2023 In this paper, we generalize and extend the Baskakov-Kantorovich operators by constructing the ( p , q ) $(p, q)$ -Baskakov Kantorovich operators ( ϒ n , b , p , q h ) ( x ) = [ n ] p , q ∑ b = 0 ∞ q b − 1 υ b , n p , q ( x ) ∫ R h ( y ) Ψ ( [ n ] p , q ...

On Kantorovich variant of Baskakov type operators preserving some functions
Filomat, 2022 This paper deals with a generalization of Kantorovich variant of Baskakov type operators preserving constant function and e-2y. We discuss uniform convergence properties and weighted approximation for this generalized Baskakov-Kantorovich type ...

STUDYING THE COSTCRITICAL DEFORMATIONS OF SHUTTER SPHERICAL PANELS OF CONSTANT THICKNESS
Bulletin of the South Ural State University series Mathematics Mechanics Physics, 2023 An algorithm for studying the stress-strain state of elastic thin-walled shell systems consisting of shells of revolution has been developed. To solve the nonlinear problem of strong bending of a thin isotropic shell of revolution, in which no ...

Operator iteration on the Young inequality
Journal 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.

Improvements of operator reverse AM-GM inequality involving positive linear maps
Journal of Inequalities and Applications, 2020 In this paper, we shall present some reverse arithmetic-geometric mean operator inequalities for unital positive linear maps. These inequalities improve some corresponding results due to Xue (J. Inequal. Appl. 2017:283, 2017).

Approximation properties of the modified Lupas-Kantorovich type operators
MATEC Web of Conferences, 2017 In this paper, the author introduce a class of modified Lupas-Kantorovich type operators which preserve constant and linear functions. By using modulus of continuity, modulus of smooth, K-functional and lipschitz class, the rate of convergence of these ...

An Inverse Result of Approximation by Sampling Kantorovich Series [PDF]
Proceedings of the Edinburgh Mathematical Society, 2018 In the present paper, an inverse result of approximation, i.e. a saturation theorem for the sampling Kantorovich operators, is derived in the case of uniform approximation for uniformly continuous and bounded functions on the whole real line.

On the Lawson–Lim means and Karcher mean for positive invertible operators
Journal of Inequalities and Applications, 2018 This note aims to generalize the reverse weighted arithmetic–geometric mean inequality of n positive invertible operators due to Lawson and Lim. In addition, we make comparisons between the weighted Karcher mean and Lawson–Lim geometric mean for higher ...

On an approximation operator and its Lipschitz constant
Journal of Numerical Analysis and Approximation Theory, 2002 In this note we consider an approximation operator of Kantorovich type in which expression appears a basic sequence for a delta operator and a Sheffer sequence for the same delta operator.
