The χ2∆fA defined by modulus - doi: 10.4025/actascitechnol.v35i3.16185

Nagarajan Subramanian


In this paper we introduce χ2∆fA sequence spaces defined by modulus function and study general properties of these spaces and also establish some inclusion results among them. Also P – statistical χ2 sequence spaces is defined and discuss about  general properties.
