Coupled fixed point results on metric spaces defined by binary operations
(Vasyl Stefanyk Precarpathian Natl Univ, 2018)In parallel with the various generalizations of the Banach fixed point theorem in metric spaces, this theory is also transported to some different types of spaces including ultra metric spaces, fuzzy metric spaces, uniform ... -
On Approximation Properties of Baskakov-Schurer-Szasz Operators Preserving Exponential Functions
(Univ Nis, Fac Sci Math, 2018)The goal of this paper is to construct a general class of operators which has known BaskakovSchurer-Szasz that preserving constant and e(2ax), a > 0 functions. Also, we demonstrate the fact that for these operators, moments ... -
A new construction of Szasz-Mirakyan operators
(Springer, 2018)The paper aims to study a generalization of Szasz-Mirakyan-type operators such that their construction depends on a function rho by using two sequences of functions. To show how the function rho play a crucial role in the ... -
A note on Szasz-Mirakyan-Kantorovich type operators preserving e(-x)
