<b>The strongly generalized double difference &chi; sequence spaces defined by a modulus</b> - doi: 10.4025/actascitechnol.v35i4.16184

Abstract

In this paper we introduce the strongly generalized difference sequence spaces of modulus function and is a non-negative four dimensional matrix of complex numbers and (pi(mn)) is a sequence of positive real numbers. We also give natural relationship between strongly generalized difference summable sequences with respect of modulus. We examine some topological properties of the above spaces and investigate some inclusion relations between these spaces.
