Approximation degree of Durrmeyer–Bézier type operators

Journal of Inequalities and Applications, 2018
Recently, a mixed hybrid operator, generalizing the well-known Phillips operators and Baskakov–Szász type operators, was introduced. In this paper, we study Bézier variant of these new operators.

Dunkl analogue of Szász-mirakjan operators of blending type

Open Mathematics, 2018
In the present work, we construct a Dunkl generalization of the modified Szász-Mirakjan operators of integral form defined by Pǎltanea [1]. We study the approximation properties of these operators including weighted Korovkin theorem, the rate of ...

High-Order AFEM for the Laplace-Beltrami Operator: Convergence Rates [PDF]

, 2016
We present a new AFEM for the Laplace-Beltrami operator with arbitrary polynomial degree on parametric surfaces, which are globally $W^1_\infty$ and piecewise in a suitable Besov class embedded in $C^{1,\alpha}$ with $\alpha \in (0,1]$.

A new kind of Bernstein-Schurer-Stancu-Kantorovich-type operators based on q-integers

Journal of Inequalities and Applications, 2017
Agrawal et al. (Boll. Unione Mat. Ital. 8:169-180, 2015) introduced a Stancu-type Kantorovich modification of the operators proposed by Ren and Zeng (Bull. Korean Math. Soc.

Response operators for Markov processes in a finite state space: radius of convergence and link to the response theory for Axiom A systems [PDF]

, 2015
Using straightforward linear algebra we derive response operators describing the impact of small perturbations to finite state Markov processes. The results can be used for studying empirically constructed—e.g.

On the rate of convergence of Baskakov-Kantorovich-Bézier operators for bounded variation functions

Journal of Numerical Analysis and Approximation Theory, 2002
In the present paper we introduce Baskakov-Kantorovich-Bézier operators and study their rate of convergence for functions of bounded variation.

The Virtual Element Method with curved edges

, 2018
In this paper we initiate the investigation of Virtual Elements with curved faces. We consider the case of a fixed curved boundary in two dimensions, as it happens in the approximation of problems posed on a curved domain or with a curved interface ...

Rate of convergence of Stancu beta operators for functions of bounded variation

Journal of Numerical Analysis and Approximation Theory, 2004
In this paper we study beta operators of second kind recently introduced by Prof. D. D. Stancu. We obtain an estimate on the rate of convergence for functions of bounded variation by means of the decomposition technique.

Binary Social Mimic Optimization Algorithm With X-Shaped Transfer Function for Feature Selection

IEEE Access, 2020
Definitive optimization algorithms are not able to solve high dimensional optimization problems when the search space grows exponentially with the problem size, and an exhaustive search also becomes impractical. To encounter this problem, researchers use

Accurate Approximation of ZF Massive MIMO Channel Rate With a Finite Antenna Over Ricean Fading Channel

IEEE Access, 2018
In a typical downlink massive multiple-input and multiple-output (massive MIMO) system, the available degree of freedom (DoF) and multiplexing gain improve the channel rate.
