(A, φ, λ)– invariant statistical convergence of order α
Savaş, Ekrem (Maltepe Üniversitesi, 2019)The aim of this paper is to introduce and present some properties of (A, ϕ, λ) invariant statistically convergent which is defined using the ϕ function and the generalized three parametric real matrix. Further some ...

A new sequence space of order α and modulus function
Savaş, Ekrem (Maltepe Üniversitesi, 2021)In this paper we introduce and study some properties of the new sequence space of order α which is defined using the modulus and ϕ function. Furthermore some connections between Vα((T, ϕ)) strong summability of sequences ... 
On double lacunary ∆σstatistical convergence of sequences of fuzzy numbers
Savaş, Ekrem (Maltepe Üniversitesi, 2009)Quite recently, Savas and Mursaleen [1] defined the statistical analogue for double sequences X = {Xk,l} of fuzzy numbers as follows: A double sequences X = {Xk,l} is said to be Pstatistically convergent to X0 provided ... 
On some new sequence spaces with an index defined by a modulus function
Savaş, Ekrem; Şevli, Hamdullah (Maltepe Üniversitesi, 2009)In this paper we define the following sequence spaces by using a modulus function, We also get some inclusion relations. Note that if f(x) = x, then we get ˆwp(f) = ˆwp and wˆˆp(f) = wˆˆp. If p = 1, then wˆp = ˆw, which ... 
On the double lacunary (A, φ)sequence spaces of order α
Savaş, Ekrem (AIP Publishing, 2019)In this paper, our goal is to extend a few results known in the literature for ordinary (single) sequences to multiply sequences of real numbers. Further we introduce an idea of double lacunary strong (A, ϕ) convergence ... 
On the double lacunary (A, φ)statistical convergence of order α
Savaş, Ekrem (AIP Publishing, 2019)In this paper, we investigate double lacunary statistical convergence of order α for multiply sequences of real numbers. Further we study some connections between double lacunary strong (A, ϕ) convergence of order α with ...

Some sequence spaces and invariant mean
Savaş, Ekrem (Maltepe Üniversitesi, 2021)The goal of this paper is to study characterization of strongly λ− invariant regular matrices, uniqueness of generalized limits and inclusion relations of such sequences have been discussed. 
σ Convergence and a new sequence space of order α
Savaş, Ekrem (Maltepe Üniversitesi, 2019)A continuous linear functional ϕ on l∞ is said to be an invariant mean or a σmean if and only if 1. ϕ(x) ≥ 0 when the sequence x = (xk) has xn ≥ 0 for all n; 2. ϕ(e) = 1 where e = (1, 1, 1, . . .) and 3. ϕ(xσ(n)) = ...
