Some Double Almost (λmμn) convergence in χ2 -Riesz spaces defined by Musielak-Orlicz functions.

In this paper we introduce and study the notions of almost (λmμn) convergence in χ2 -Riesz spaces; strongly p - convergence, Cesaro strongly p - convergence with respect to a Musielak-Orlicz functions and examine some properties of the resulting sequence spaces. We also introduce and study the statistical convergence of almost (λmμn) convergence in χ2 -Riesz spaces and also some inclusion theorems are discussed. [ABSTRACT FROM AUTHOR]
