On the Muntz Rational Approximation Rate [PDF]

Proceedings of the American Mathematical Society, 1994
The present paper constructs a counterexample to show that a conjecture of Newman concerning rational approximation rate of arbitrary Markov system is generally not true.

Probability of noise- and rate-induced tipping [PDF]

, 2017
We propose an approximation for the probability of tipping when the speed of parameter change and additive white noise interact to cause tipping. Our approximation is valid for small to moderate drift speeds and helps to estimate the probability of false

Generalized ( p , q ) $(p,q)$ -Bleimann-Butzer-Hahn operators and some approximation results

Journal of Inequalities and Applications, 2017
The aim of this paper is to introduce a new generalization of Bleimann-Butzer-Hahn operators by using ( p , q ) $(p,q)$ -integers which is based on a continuously differentiable function μ on [ 0 , ∞ ) = R + $[0,\infty)=\mathbb{R}_{+}$ . We establish the

Rate Of Convergence In Approximation

Periodica Mathematica Hungarica, 2014
In the present paper we give a Korovkin type approximation theorem for a sequence of positive linear operators acting from into itself using the concept of -summation processes. We also study the rate of convergence of these operators.

Approximation by q-analogue of modified Jakimovski-Leviatan-Stancu type operators

Demonstratio Mathematica, 2017
In this paper, we introduce the q-analogue of the Jakimovski-Leviatan type modified operators introduced by Atakut with the help of the q-Appell polynomials.We obtain some approximation results via the well-known Korovkin’s theorem for these operators.We

Rate of Approximation for Modified Lupaş-Jain-Beta Operators

Journal of Function Spaces, 2020
The main intent of this paper is to innovate a new construction of modified Lupaş-Jain operators with weights of some Beta basis functions whose construction depends on σ such that σ0=0 and infx∈0,∞σ′x≥1.

Pointwise approximation of 2 π/r-periodic functions by matrix operators of their Fourier series with r-differences of the entries

Demonstratio Mathematica, 2018
We extend the results of Xh. Z. Krasniqi [Acta Comment. Univ. Tartu. Math., 2013, 17, 89-101] and the authors [Acta Comment. Univ. Tartu. Math., 2009, 13, 11-24] to the case of 2 π/r-periodic functions.

Modified Bernstein–Durrmeyer Type Operators

Mathematics, 2022
We constructed a summation–integral type operator based on the latest research in the linear positive operators area. We establish some approximation properties for this new operator.

Some Upper Bounds for RKHS Approximation by Bessel Functions

Axioms, 2022
A reproducing kernel Hilbert space (RKHS) approximation problem arising from learning theory is investigated. Some K-functionals and moduli of smoothness with respect to RKHSs are defined with Fourier–Bessel series and Fourier–Bessel transforms ...
