This Ph. D. study presents an experimental investigation on the effect of binary, ternary and
quartet combinations of fly ash (FA), silica fume (SF), ground granulated blast furnace slag …

Several papers, mainly written by J. de la Call and co-authors, contain modifications of
classical sequences of positive linear operators to obtain new sequences converging to …

In this work, we present a Durrmeyer-type operator having the basis functions in summation
and integration due to Aral (Math Commun 24: 119–131, 2019) and Pǎltǎnea (Carpath J …

In this work, we construct a Durrmeyer type modification of the τ-Baskakov operators
depends on two parameters α> 0 α>0 and τ∈ 0, 1 τ∈0,1. We derive the rate of …

The idea behind Poisson approximation to the binomial distribution was used in de la Cal
and Luquin (J Approx Theory 68 (3): 322–329, 1992) and subsequent papers in order to …

A discrete operators based on the modified Laguerre polynomials is studied here. As per our
knowledge approximation of these operators have not been studied earlier. We find the …

The main objective of this paper is to construct a new sequence of operators involving
Apostol-Genocchi polynomials based on certain parameters. We investigate the rate of …

The concept of approximation concerning positive and linear operators was initiated with the
two well-known results due to Weierstrass and Korovkin. During the last century, after the …

In the present paper, we discuss the approximation behavior of certain exponential type
operator. These operators were not studied earlier by researchers due to its complicated …

It is well-known that Lupaş operators are not exponential type operators, although they
preserve linear functions. The differential operator is not applicable to estimate nice …
