The Backward Operator of Double Almost (λmμn) Convergence in χ2-Riesz Space Defined By a Musielak-Orlicz Function

Abstract

In this paper we introduce the backward operator is del and study the notion backward operator of del-statistical convergence and backward operator of del- statistical Cauchy sequence using by almost (lambda(m)mu(n)) convergence in chi(2)-Riesz space and also some inclusion theorems are discussed.
