Abstract

A real valued function defined on a subset EE of R\mathbb{R}, the set of real numbers, is ρ\rho-statistically downward continuous if it preserves ρ\rho-statistical downward quasi-Cauchy sequences of points in EE, where a sequence (αk)(\alpha_{k}) of real numbers is called ρ{\rho}-statistically downward quasi-Cauchy if limn1ρn{kn:Δαkε}=0\lim_{n\rightarrow\infty}\frac{1}{\rho_{n} }|\{k\leq n: \Delta \alpha_{k} \geq \varepsilon\}|=0 for every ε>0\varepsilon>0, in which (ρn)(\rho_{n}) is a non-decreasing sequence of positive real numbers tending to \infty such that lim supnρnn<\limsup _{n} \frac{\rho_{n}}{n}<\infty , Δρn=O(1)\Delta \rho_{n}=O(1), and Δαk=αk+1αk\Delta \alpha _{k} =\alpha _{k+1} - \alpha _{k} for each positive integer kk. It turns out that a function is uniformly continuous if it is ρ\rho-statistical downward continuous on an above bounded set.
