Abstract Korovkin theory in modular spaces in the sense of power series method
Yurdakadim, Tuğba (2018)In this paper, using the power series method we obtain an abstract Korovkin type approximation theorem for a sequence of positive linear operators dened on modular spaces. -
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 ... -
Core Theorems in The Generalized Statistical Sense
Taş, Emre; Yurdakadim, Tuğba (2018)The main purpose of the paper is to give some results concerning with the generalized statistical core of a bounded sequence via B-statistical convergence where B = (Bi) is a sequence of infinite matrices. We characterize ... -
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 ... -
Some results concerning the summability of spliced sequences
Yurdakadim, Tuğba; Ünver, Mehmet (TUBİTAK, 2016)A spliced sequence is formed by combining all of the terms of two or more convergent sequences, in their original order, into a new spliced sequence. In this paper replacing convergent sequences by bounded sequences, we ... -
Some results for max-product operators via power series method
Yurdakadim, Tuğba; Taş, Emre (Univerzita Komenskeho, 2018)In this paper, we obtain an approximation theorem by max-product operators with the use of power series method which is more effective than ordinary convergence and includes both Abel and Borel methods. We also estimate ... -
Some results on uniform statistical cluster points
Yurdakadim, Tuğba; Miller-Van-Wieren, Leila (TUBİTAK, 2017)In this paper, we present some results linking the uniform statistical limit superior and inferior, almost convergence and uniform statistical convergence of a sequence. We also study the relationship between the set of ...
