强缺项拟柯西性的新研究

A new study on the strongly lacunary quasi Cauchyness

Huseyin Kaplan, Huseyin Cakalli

摘要:

本文引入了$N_θ^{2}$拟柯西序列的概念。证明了与$N_θ^{2}$ -拟柯西序列有关的一些有趣的定理。定义在$\mathbb{R}$的子集$A$(实数集)上的实值函数$f$在$A$上是$N_θ^{2}$ ward连续的,如果它保持$A$中的点的$N_θ^{2}$拟柯西序列,即,只要$(α_{k})$是$A$中的点的$N_θ^{2}$拟柯西序列,$(f( α_{k}))$就是$N_θ^{2}$拟柯西序列,其中,如果$(Δ^{2} α_{k})$是$N_θ$拟柯西序列,则序列$(α_{k})$被称为$N_θ^{2}$拟柯西,其中对于每个正整数$k$,$Δ^{2}α_{k}=α_{k+2}-2α_{k+1}+α_{k}$。

英文摘要:

In this paper, the concept of an $N_θ^{2}$ quasi-Cauchy sequence is introduced. We proved interesting theorems related to $N_θ^{2}$-quasi-Cauchy sequences. A real valued function $f$ defined on a subset $A$ of $\mathbb{R}$, the set of real numbers, is $N_θ^{2}$ ward continuous on $A$ if it preserves $N_θ^{2}$ quasi-Cauchy sequences of points in $A$, i.e. $(f( α_{k}))$ is an $N_θ^{2}$ quasi-Cauchy sequence whenever $(α_{k})$ is an $N_θ^{2}$ quasi-Cauchy sequences of points in $A$, where a sequence $(α_{k})$ is called $N_θ^{2}$ quasi-Cauchy if $(Δ^{2} α_{k})$ is an $N_θ$ quasi-Cauchy sequence where $Δ^{2}α_{k}=α_{k+2}-2α_{k+1}+α_{k}$ for each positive integer $k$.
