چکیده
In this article we introduce the notion of η−dual of double sequence spaces. We find the η− dual of some double sequence spaces. We verify the perfectness of different double sequence spaces relative to η− dual.

Some Paranormed Difference Double Sequence Spaces Defined by Orlicz Function
In this article we introduce some vector valued difference paranormed double sequence spaces defined by Orlicz function. We study some of their properties like solidness, symmetricity, completeness etc. and prove some inclusion results.
متن کاملOn Some Classes of Difference Double Sequence Spaces
In this article we introduce the difference double sequence spaces 2`∞(∆, q), 2c(∆, q), 2c0(∆, q), 2c(∆, q), 2c0 (∆, q), 2c (∆, q) and 2c0 (∆, q) defined over a seminormed space (X, q), seminormed by q. We examine some topological and algebraic properties of these spaces like symmetricity, solidness, monotonocity, convergence free, nowhere densenes etc. We prove some inclusion results too.

In this article we introduce some statistically convergent difference double sequence spaces defined by Orlicz function. Completeness of the spaces will be proved. We study some of their other properties like solidness, symmetricity etc. and prove some inclusion results.
متن کاملOn Some Generalized New Type Difference Sequence Spaces Defined by a Modulus Function in a Seminormed Space
The idea of difference sequence spaces were introduced by Kizmaz [6] and generalized by Et. and Colak [4]. Later Tripathy, Esi and Tripathy [15] introduced the notion of the new difference operator ∆m for n,m ∈ N . In this paper we introduced some new type of generalized difference sequence spaces defined by a modulus function and the new type of statistically convergent generalized difference ...
