λ-Bernstein Operators Based on Pólya Distribution

Numerical Functional Analysis and Optimization, 2023
In this manuscript, we propose a Pólya distribution-based generalization of -Bernstein operators. We establish some fundamental results for convergence as well as order of approximation of the proposed operators.

On a class of hypoelliptic operators with unbounded coefficients in ${\matbb R}^N$

, 2008
We consider a class of non-trivial perturbations ${\mathscr A}$ of the degenerate Ornstein-Uhlenbeck operator in ${\mathbb R}^N$. In fact we perturb both the diffusion and the drift part of the operator (say $Q$ and $B$) allowing the diffusion part to be

FAT-based robust adaptive controller design for electrically direct-driven robots using Phillips q-Bernstein operators

Robotica (Cambridge. Print), 2022
This article proposes a robust and adaptive controller for industrial robot arms with multiple degrees of freedom without the need for velocity measurement.

Modified ρ-Bernstein Operators for Functions of Two Variables

Numerical Functional Analysis and Optimization, 2021
In this manuscript, we consider a bivariate extension of modified ρ-Bernstein operators and obtain Voronovskaya type and Grüss Voronovskaya type theorems for these operators.

Probabilistic degenerate Bernstein polynomials

Applied Mathematics in Science and Engineering
In recent years, both degenerate versions and probabilistic extensions of many special numbers and polynomials have been explored. For instance, degenerate Bernstein polynomials and probabilistic Bernstein polynomials were investigated earlier.

Recursive Bernstein operators and degenerate diffusion processes

2002
We study a new sequence of Bernstein-type operators on the \(d\)-dimensional simplex. The binomial coefficients considered in the classical definition are substituted with more general ones satisfying a similar recursive formula and this produces a first-order perturbation term in the Voronovskaja formula.

Approximation by Riemann–Liouville type fractional α$$ \alpha $$ ‐Bernstein–Kantorovich operators

Mathematical methods in the applied sciences
In this research paper, we construct a new sequence of Riemann–Liouville type fractional α$$ \alpha $$ ‐Bernstein–Kantorovich operators. We prove a Korovkin type approximation theorem and discuss the rate of convergence with the first order modulus of ...
