Approximation by positive linear operators in modular spaces by power series method
Taş, Emre; Yurdakadim, Tuğba (Birkhauser Verlag AG, 2017)In the present paper, we study the problem of approximation to a function by means of positive linear operators in modular spaces in the sense of power series method. Indeed, in order to get stronger results than the ... -
Approximation to derivatives of functions by linear operators acting on weighted spaces by power series method
Taş, Emre; Yurdakadim, Tuğba (Springer New York LLC, 2016)In this chapter, using power series method we study some Korovkin type approximation theorems which deal with the problem of approximating a function by means of a sequence of linear operators acting on weighted spaces. © ... -
The Arzelà-Ascoli theorem by means of ideal convergence
Taş, Emre; Yurdakadim, Tuğba (De Gruyter, 2018)In this paper, using the concept of ideal convergence, which extends the idea of ordinary convergence and statistical convergence, we are concerned with the I-uniform convergence and the I-pointwise convergence of sequences ... -
Inclusion results on statistical cluster points
Miller, Harry I.; Wieren, Leila Miller Van; Taş, Emre; Yurdakadim, Tuğba (Springer Netherlands, 2016)We study the concepts of statistical cluster points and statistical core of a sequence for Aλ methods defined by deleting some rows from a nonnegative regular matrix A. We also relate Aλ-statistical convergence to ... -
Korovkin type approximation theorems in weighted spaces via power series method
Taş, Emre; Yurdakadim, Tuğba; Girgin Atlıhan, Özlem (Element D.O.O., 2018)In this paper we consider power series method which is also member of the class of all continuous summability methods. We study a Korovkin type approximation theorem for a sequence of positive linear operators acting from ... -
Some inequalities between functionals related to generalized limits
Yurdakadim, Tuğba; Orhan, Cihan (Editura Academiei Romane, 2017)Recall that A-statistical core theorem determines a class of regular matrices for which lim sup(T x) ≤ stA − lim sup x for all x ∈ m. The main object of this paper is to study an inequality between functionals which is ... -
Some Korovkin type results via power series method in modular spaces
Yurdakadim, Tuğba (Ankara University, 2016)Abstract. In this paper, we obtain a Korovkin type approximation result for a sequence of positive linear operators deÖned on modular spaces with the use of power series method . We also provide an example which satisfies ...
