SOME NEW TYPE OF DIFFERENCE SEQUENCE SPACES DEFINED BY MODULUS FUNCTION AND STATISTICAL CONVERGENCE

摘要

In this article we introduce the difference sequence spaces W 0 [f,Δm ],W 1 [f,Δm ],W∞[f,Δm ] and S[f,Δm ],defined by a modulus function f.We obtain a relation between W 1 [f,Δm ] ∩l∞[f,Δm ] and S[f,Δm ] ∩l∞[f,Δm ] and prove some inclusion results.
