Ibragimov–Gadjiev operators preserving exponential functions

Journal of Inequalities and Applications
In this paper, a modification of general linear positive operators introduced by Ibragimov and Gadjiev in 1970 is constructed. It is shown that this modification preserves exponential mappings and also contains modified Bernstein-, Szász- and Baskakov ...

Weighted Approximation by Szász–Mirakyan–Durrmeyer Operators Reproducing Exponential Functions

Mathematics
We examine a Szász–Mirakyan–Durrmeyer type operator that reproduces the functions 1 and e2ax for a fixed parameter a>0. While its exponential reproduction property has been described in the classical literature, the effect of exponential weights on its ...

Approximation by q-Post-Widder Operators Based on a New Parameter

Abstract and Applied Analysis
The purpose of this paper is to introduce q-Post–Widder operators based on a new parameter and study their approximation properties. The moments and central moments are investigated.
