New Subclass of Analytic Function Related with Generalized Conic Domain Associated with q− Differential Operator

Journal of Mathematics, Volume 2022, Issue 1, 2022., 2022
The quantum (or q‐) calculus is widely applied in various operators which include the q‐difference (q‐derivative) operator, and this operator plays an important role in geometric function theory (GFT) as well as in the theory of hypergeometric series. In our present investigation, we introduce and study q‐differential operator associated with q‐Mittag ...

Approximation Properties and q‐Statistical Convergence of Stancu‐Type Generalized Baskakov‐Szász Operators

Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022
In this article, we introduce Stancu‐type modification of generalized Baskakov‐Szász operators. We obtain recurrence relations to calculate moments for these new operators. We study several approximation properties and q‐statistical approximation for these operators.

On Shape Parameter α‐Based Approximation Properties and q‐Statistical Convergence of Baskakov‐Gamma Operators

Journal of Mathematics, Volume 2022, Issue 1, 2022., 2022
We construct a novel family of summation‐integral‐type hybrid operators in terms of shape parameter α ∈ [0,1] in this paper. Basic estimates, rate of convergence, and order of approximation are also studied using the Korovkin theorem and the modulus of smoothness.

Applications of q‐Symmetric Derivative Operator to the Subclass of Analytic and Bi‐Univalent Functions Involving the Faber Polynomial Coefficients

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
In this paper, using the basic concepts of symmetric q‐calculus operator theory, we define a symmetric q‐difference operator for m‐fold symmetric functions. By considering this operator, we define a new subclass ℛb(φ, m, q) of m‐fold symmetric bi‐univalent functions in open unit disk U. As in applications of Faber polynomial expansions for fm ∈ ℛb(φ, m,

Premedication practices for neonatal tracheal intubation: Results from the EPIPPAIN 2 prospective cohort study and comparison with EPIPPAIN 1

Paediatric and Neonatal Pain, Volume 3, Issue 2, Page 46-58, June 2021., 2021
Abstract To describe the frequency and nature of premedication practices for neonatal tracheal intubation (TI) in 2011; to identify independent risk factors for the absence of premedication; to compare data with those from 2005 and to confront observed practices with current recommendations.

On the Lattice Properties of Almost L‐Weakly and Almost M‐Weakly Compact Operators

Journal of Function Spaces, Volume 2021, Issue 1, 2021., 2021
We establish the domination property and some lattice approximation properties for almost L‐weakly and almost M‐weakly compact operators. Then, we consider the linear span of positive almost L‐weakly (resp., almost M‐weakly) compact operators and give results about when they form a Banach lattice and have an order continuous norm.

Approximation by Durrmeyer-type operators [PDF]

Annales Polonici Mathematici, 1996
The authors consider the operators \[ M_n(f,x)= \sum^\infty_{k=0} p_{n,k}(x)\int^\infty_0 b_{n,k}(t)f(t)dt, \] where \(p_{n,k}(x)= (-1)^k{x^k\over k!} \phi^{(k)}_n(x)\), \(b_{n,k}(t)= (-1)^{k+1}{t^k\over k!} \phi^{(k+1)}_n(t)\) and \[ \phi_n(x)= \begin{cases} (1+cx)^{-n/c} & \text{for the interval }[0,\infty)\text{ with }c>0\\ e^{-nx} & \text{for the ...

Differences of Positive Linear Operators on Simplices

Journal of Function Spaces, Volume 2021, Issue 1, 2021., 2021
The aim of the paper is twofold: we introduce new positive linear operators acting on continuous functions defined on a simplex and then estimate differences involving them and/or other known operators. The estimates are given in terms of moduli of smoothness and K‐functionals. Several applications and examples illustrate the general results.

Applications of a New q‐Difference Operator in Janowski‐Type Meromorphic Convex Functions

Journal of Function Spaces, Volume 2021, Issue 1, 2021., 2021
The main aim of the present article is the introduction of a new differential operator in q‐analogue for meromorphic multivalent functions which are analytic in punctured open unit disc. A subclass of meromorphic multivalent convex functions is defined using this new differential operator in q‐analogue.
