On Kothe-Toeplitz and Null Duals of Some Difference Sequence Spaces Defined by Orlicz Functions

Hemen Dutta

Abstract

The main aim of this paper is to compute Kothe-Toeplitz and null duals of some difference sequence spaces, defined by means of a fixed equence of multiplier and by an Orlicz function. Further the coincidence for three pairs of analogous spaces is established.

Keywords
