On the rate of convergence for the q-durrmeyer polynomials in complex domains
Gürel, Övgü; Ostrovska, Sofiya; Turan, Mehmet (Walter de Gruyter, 2024)The q-Durrmeyer polynomials are one of the popular q-versions of the classical operators of approximation theory. They have been studied from different points of view by a number of researchers. The aim of this work is to ... -
The saturation of convergence for the complex q-durrmeyer polynomials
Gürel, Övgü; Ostrovska, Sofiya; Turan, Mehmet (Springer, 2025)The aim of this paper is to establish a saturation result for the complex q-Durrmeyer polynomials (Dn,qf)(z), where q∈(0,1), f∈C[0,1]. It is known that the sequence {(Dn,qf)(z)}n∈N converges uniformly on any compact set ...
