f -- Lacunary Statistical Convergence Of Order (α, β).

The main purpose of this paper is to introduce the concepts of f-lacunary statistical convergence of order (α, β) and strong f--lacunary summability of order (α, β) of sequences of real numbers for 0 < a ≤ β ≤ 1, where f is an unbounded modulus. [ABSTRACT FROM AUTHOR]
