Theory of Some Sequence Spaces and Matrix Transformations: A Review

A comprehensive review of matrix transformations in sequence spaces

Abstract

In most cases the most general linear operator from one sequence space into another is actually given by an infinite matrix and therefore the theory of matrix transformations has always been of great interest in the study of sequence spaces. The study of general theory of matrix transformations was motivated by the special results in summability theory. This paper is a review article which gives almost all known results on matrix transformations.
