Abstract

In this paper, we introduce a concept of statistically pp-quasi-Cauchyness of a real sequence in the sense that a sequence (αk)(\alpha_{k}) is statistically pp-quasi-Cauchy if limn1n{kn:αk+pαkε}=0\lim_{n\rightarrow\infty}\frac{1}{n}|\{k\leq n: |\alpha_{k+p}-\alpha_{k}|\geq{\varepsilon}\}|=0 for each ε>0\varepsilon>0. A function ff is called statistically pp-ward continuous on a subset AA of the set of real umbers R\mathbb{R} if it preserves statistically pp-quasi-Cauchy sequences, i.e. the sequence f(x)=(f(αn))f(\textbf{x})=(f(\alpha_{n})) is statistically pp-quasi-Cauchy whenever α=(αn)\boldsymbol\alpha=(\alpha_{n}) is a statistically pp-quasi-Cauchy sequence of points in AA. It turns out that a real valued function ff is uniformly continuous on a bounded subset AA of R\mathbb{R} if there exists a positive integer pp such that ff preserves statistically pp-quasi-Cauchy sequences of points in AA.
