Let λ = (λn)n≥1be a nondecreasing sequence of positive numbers tending to infinity such that λ1 = 1 and λn+1 ≥ λn + 1 for all n, and let In = [n -- λn + 1; n] for n = 1; 2;,.... Then for any given nonzero sequence µ, we define by Δ+(µ) the operator that generalizes the operator of the First difference and is defined by Δ+(µ)xk = µk(xk -- xk+1). In this article, for any given integer r ≤ 1, we deal with the λ+r(µ)-statistical convergence that generalizes in a certain sense the well-known λE-rstatistical convergence, main results consist in determining sets of sequences χ and χ' of the form sξ0 satisfying χ ⊂ [V; λ]0(Δ+r(µ)) ⊂ χ' and sets κ and κ' of the form sξ satisfying χ ⊂ [V, λ]∞(Δ+r(µ)) ≥ κ'. This study is justified since the infinite matrix associated with the operator Δ+r(µ) cannot be explicitly calculated for all r. [ABSTRACT FROM AUTHOR]
