Iterates of q-Bernstein operators on triangular domain with all curved sides
In this article, Phillips-type Bernstein operators (ℬm,qtF)(t,s)({{\mathcal{ {\mathcal B} }}}_{m,q}^{t}F)\left(t,s) and (ℬn,qsF)(t,s)({{\mathcal{ {\mathcal B} }}}_{n,q}^{s}F)\left(t,s), their products, and Boolean sum based on q-integer have been studied

About a dubious proof of a correct result about closed Newton Cotes error formulas
In this study, we comment about a wrong proof, at least incomplete, of the closed Newton Cotes error formulas for integration in a closed interval [a,b].\left[a,b].

Strict positive definiteness on spheres via disk polynomials
We characterize complex strictly positive definite functions on spheres in two cases, the unit sphere of ℂq, q ≥ 3, and the unit sphere of the complex ℓ2. The results depend upon the Fourier‐like expansion of the functions in terms of disk polynomials and, among other things, they enlarge the classes of strictly positive definite functions on real ...

Integral representations for Padé‐type operators
The main purpose of this paper is to consider an explicit form of the Padé‐type operators. To do so, we consider the representation of Padé‐type approximants to the Fourier series of the harmonic functions in the open disk and of the L p‐functions on the circle by means of integral formulas, and, then we define the corresponding Padé‐type operators. We

A note on the rate of convergence for Chebyshev-Lobatto and Radau systems
This paper is devoted to Hermite interpolation with Chebyshev-Lobatto and Chebyshev-Radau nodal points. The aim of this piece of work is to establish the rate of convergence for some types of smooth functions.

Stečkin inequalities for summability methods
Stečkin proved an inequality on Fejér means of Fourier series He said, “Proving similar inequality for other summability method is an interesting problem.” We generalize Stečkin′s inequality and give various applications to summability methods.

The growth, spread, and mutation of internet phenomena: A study of memes
An internet memes is defined as “an image, video, piece of text, etc., typically humorous in nature, that is copied and spread rapidly by Internet users, often with slight variations” (Oxford Living Dictionary, 2018). Such units of information are spread

The Paley‐Wiener‐Levinson theorem revisited
In this paper a new proof of the Paley‐Wiener‐Levinson theorem is presented. This proof is based upon the isometry between the Paley‐Wiener space and that of the square‐integrable functions in [−π, π], on one hand, and a Titchmarsh′s theorem which allows recovering bandlimited, entire functions from their zeros, on the other hand.
