Approximation by Durrmeyer Type Exponential Sampling Operators
Numerical Functional Analysis and Optimization, 2022In the present article, we derive some approximation results concerning the order of convergence for a family of Durrmeyer type exponential sampling operators.

Multivariate Exponential Operators
Studies in Applied Mathematics, 1980An unexpected connection between a certain class of exponential approximation operators and polynomial sequences of binomial type was discovered by Ismail. Building on this result, we present a multivariate analogue of these exponential operators.

Pointwise Estimate for Exponential-Type Operators
Southeast Asian Bulletin of Mathematics, 2000The authors obtain a pointwise estimate for three general exponential-type operators by using the concept of Ditzian-Totik modulus of smoothness.

Error Bounds for Exponential Operator Splittings
BIT Numerical Mathematics, 2000The authors obtain error bounds for Strang splittings involving unbounded operators. They apply the results to a numerical method for the Schrödinger equation, in which the Laplacian is discretized by a Fourier method.

Reconstruction of Baskakov operators preserving some exponential functions
Mathematical methods in the applied sciences, 2018The present paper deals with a new modification of Baskakov operators in which the functions exp(μt) and exp(2μt), μ>0 are preserved. Approximation properties of the operators are captured, ie, uniform convergence and rate of convergence of the operators

Exponentiating a Bundle of Linear Operators
Set-Valued Analysis, 2006Let \(X\) be a real Banach space, \(L(X)\) the space of all linear continuous operators from \(X\) to \(X\), endowed with its sup norm, let \(\Xi\subseteq L(X)\) and let \(F:X\rightrightarrows X\), given by \(F(x)=\{Ax \mid A\in \Xi\}\) for each \(x\in X\).

Exponential Structures and Polynomial Operators
2021We shall start by studying the generating function of the sequence of polynomials $$\displaystyle \sigma _n ( x ) = \sum _{k=1}^n S_{n,k} x^k ~. $$

Szász–Mirakyan Type Operators Which Fix Exponentials
Results in Mathematics, 2017In the last years several sequences of positive linear operators were constructed, in order to approximate larger classes of functions and/or to furnish a better rate of convergence. Some references in this direction are given in the introduction of this paper.
