Abstract

Bu makalede istatistiksel boşluklu d2-quasi-Cauchy dizisi kavramı
tanımlanmış ve araştırılmıştır. Bu araştırmada istatistiksel
boşluklu
d2-süreklilik ile ilgili ilgi
çekici teoremler ispatlanmıştır. (D2xk) istatistiksel boşluklu quasi
Cauchy dizisi olduğunda (xk) dizisine istatistiksel
boşluklu
d2-quasi-Cauchy dizisi dendiğine
göre, reel sayılar kümesinin bir alt kümesi üzerinde tanımlı reel değerli bir f
fonksiyonuna eğer terimleri A da olan istsatistiksel boşluklu d2-quasi-Cauchy dizilerini koruyor
ise, yani (xk) dizisi terimleri A da olan istatistiksel
boşluklu
d2-quasi-Cauchy dizisi olduğunda (f(xk))
dizisi de istatistiksel boşluklu d2-quasi-Cauchy dizisi oluyor ise istatistiksel boşluklu d2-ward süreklidir denir. İstatistiksel boşluklu d2-ward sürekli fonksiyonların
kümesinin sürekli fonksiyonlar uzayının kapalı bir alt kümesi olduğu ortaya çıkarılmıştır.

Lacunary statistical delta 2 quasi Cauchy sequences

Abstract

The
notion of a lacunary statistical d2-quasi-Cauchyness of sequence of
real numbers is introduce and investigated. In this work, we present
interesting theorems related to lacunary statistically d2-ward continuity. A function f, whose
domain is included in R, and whose range included in R is called lacunary
statistical d2 ward continuous if it preserves
lacunary statistical d2 quasi-Cauchy sequences, i.e.
(f(xk)) is a lacunary statistically d2 quasi-Cauchy sequence whenever (xk)
is a lacunary statistically d2 quasi-Cauchy sequence,
where  a sequence (xk) is
called lacunary statistically d2 quasi-Cauchy if (D2 xk) is a lacunary
statistically quasi-Cauchy sequence. We find out that the set of lacunary
statistical d2 ward continuous functions is closed
as a subset of the set of continuous functions.
