Abstract

A sequence of real numbers {xn}nN\{x_{n}\}_{n\in \mathbb{N}} is said to be αβ\alpha \beta-statistically convergent of order γ\gamma (where 0<γ10<\gamma\leq 1) to a real number xx \cite{a} if for every δ>0,\delta>0, limn1(βnαn+1)γ {k[αn,βn]:xkxδ}=0.\underset{n\rightarrow \infty} {\lim} \frac{1}{(\beta_{n} - \alpha_{n} + 1)^\gamma}~ |\{k \in [\alpha_n,\beta_n] : |x_{k}-x|\geq \delta \}|=0. where {αn}nN\{\alpha_{n}\}_{n\in \mathbb{N}} and {βn}nN\{\beta_{n}\}_{n\in \mathbb{N}} be two sequences of positive real numbers such that {αn}nN\{\alpha_{n}\}_{n\in \mathbb{N}} and {βn}nN\{\beta_{n}\}_{n\in \mathbb{N}} are both non-decreasing, βnαn\beta_{n}\geq \alpha_{n}  nN,\forall ~n\in \mathbb{N}, (βnαn)\beta_{n}-\alpha_{n})\rightarrow \infty as n.n\rightarrow \infty. In this paper we study a related concept of convergences in which the value xkx|x_{k}-x| is replaced by P(XkXε)P(|X_{k}-X|\geq \varepsilon) and E(XkXr)E(|X_{k}-X|^{r}) repectively (Where X,XkX, X_k are random variables for each kNk\in \mathbb{N}, ε>0\varepsilon>0, PP denote the probability, EE denote the expectation) and we call them αβ\alpha \beta-statistical convergence of order γ\gamma in probability and αβ\alpha\beta-statistical convergence of order γ\gamma in r\mboxthr^{\mbox{th}} expectation respectively. The results are applied to build the probability distribution for αβ\alpha\beta-strong pp-Ces\mboxaˋ\grave{\mbox{a}}ro summability of order γ\gamma in probability and αβ\alpha\beta-statistical convergence of order γ\gamma in distribution. Our main objective is to interpret a relational behavior of above mentioned four convergences.
