Approximation properties of Kantorovich type q-Balázs-Szabados operators
Demonstratio Mathematica, 2019 In this paper, we introduce a new kind of q-Balázs-Szabados-Kantorovich operators called q-BSK operators. We give a weighted statistical approximation theorem and the rate of convergence of the q-BSK operators.

This paper studies production economies in a commodity space that is an ordered locally convex space. We establish a general theorem on the existence of equilibrium without requiring that the commodity space or its dual be a vector lattice.

General equilibrium analysis in ordered topological vector spaces [PDF]
The second welfare theorem and the core-equivalence theorem have been proved to be fundamental tools for obtaining equilibrium existence theorems, especially in an infinite dimensional setting.

Third order convergence theorem for a family of Newton like methods in Banach space
Journal of Numerical Analysis and Approximation Theory, 2014 In this paper, we propose a family of Newton-like methods in Banach space which includes some well known third-order methods as particular cases. We establish the Newton-Kantorovich type convergence theorem for a proposed family and get an error estimate.

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.

Approximation properties by shifted knots type of α-Bernstein–Kantorovich–Stancu operators
Journal of Inequalities and ApplicationsThrough the real polynomials of the shifted knots, the α-Bernstein–Kantorovich operators are studied in their Stancu form, and the approximation properties are obtained.

Approximation Theorems for Complex $$\alpha $$-Bernstein–Kantorovich Operators
Results in MathematicsAbstractIn this paper, we introduce the complex form of$$\alpha $$α-Bernstein–Kantorovich operators. Respectively, upper quantitative estimates for the complex$$\alpha $$α-Bernstein–Kantorovich operator and its derivatives, Voronovskaya type result and the exact order of approximation of these operators are studied.

On a Kantorovich Variant of (p,q)-Szász-Mirakjan Operators
Journal of Function Spaces, 2016 We propose a Kantorovich variant of (p,q)-analogue of Szász-Mirakjan operators. We establish the moments of the operators with the help of a recurrence relation that we have derived and then prove the basic convergence theorem.

Journal of Inequalities and Applications, 2017 In this paper, we construct a bivariate tensor product generalization of Kantorovich-type Bernstein-Stancu-Schurer operators based on the concept of ( p , q ) $(p, q)$ -integers.
