Abstract:In this paper, it is introduced the concept of lacunary statistical convergence with respect to a fuzzy norm by using lacunary statistical convergence of a sequence and statistical convergent of a sequence with respect to fuzzy norm. It also has studied the relation between these concepts.
Bu çalışmada çift dizilerin lacunary ideal yakınsaklığı fuzzy n-norm kullanarak yeniden tanımlanmıştır. Çalışmada ilk olarak fuzzy n-normlu uzaylarda çift diziler için lacunary ideal yakınsaklık kavramına yer verilmiş, daha sonra bu yakınsama ile ilgili temel teoremlere değinilmiştir. İkinci olarak-yakınsaklık kavramını fuzzy n-normlu uzaylarda çift diziler için tanıtıp,-yakınsaklık ile lacunary ideal yakınsaklık arasındaki ilişki fuzzy n-normlu uzaylarda çift diziler için incelenmiştir. Son olarak, fuzzy n-normlu uzaylarda 2-Cauchy ve ℐ 2-Cauchy kavramları ve bu kavramlarla ilgili teoremlerin ifadeleri verilmiştir.
In this study, first, lacunary convergence of double sequences is introduced in fuzzy normed spaces, and basic definitions and theorems about lacunary convergence for double sequences are given in fuzzy normed spaces. Then, we introduce the concept of lacunary ideal convergence of double sequences in fuzzy normed spaces, and the relation between lacunary convergence and lacunary ideal convergence is investigated for double sequences in fuzzy normed spaces. Finally, in fuzzy normed spaces, we give the concept of limit point and cluster point for double sequences, and the theorems related to these concepts are given.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
