On some classes of generalized difference paranormed sequence spaces associated with multiplier sequences

open access: yes, 2008
In this article we introduce the generalized difference paranormed sequence spaces co(?n, ?, p), c(?n, ?, p), and l?(?n, ?, p)associated with the multiplier sequence ? = ?k of nonzero complex numbers.

On 2 - normed space valued paranormed null sequence space

open access: yesBIBECHANA, 2013
In this paper we introduce and study a new class c0 ( S, α‾ , u‾ , ||. , .|| ) of sequences with values in 2- normed space as a generalization of basic null sequence space c0. We investigate some conditions pertaining to the containment relations of the class c0 ( S, α‾ , u‾ , ||.

A NEW PARANORMED SPACE DERIVED FROM THE JORDAN TOTIENT FUNCTION AND CHARACTERIZATIONS OF SOME MATRIX TRANSFORMATIONS [PDF]

open access: yes
Paranormed linear spaces have many important properties, since they appear as the generalizations of normed linear spaces. The most well-known paranormed linear P space among these spaces is ℓ(p) space of  the sequences x=(x_{k}) satisfying ∑_{k=0 ...

Some properties of measures of noncompactness in paranormed spaces

open access: yes, 1988
This paper presents new properties of important measures of noncompactness in paranormed spaces. Using these properties some fixed point theorems for multivalued mappings in general topological vector spaces are obtained in a straightforward way.

A study of the q-analogue of the paranormed Cesàro sequence spaces

open access: yesFilomat
In this article, we introduce and investigate the q-Ces?ro matrix C(q) = (cq uv) with q ? (0, 1) for which we have cq uv ={qv/[u + 1]q (0 ? v ? u) 0 (v > u), where the q-number [?]q is given, as usual in the q-theory, by [?]q := {1 ? q?/1 ? q (? ? C) ?n?1 k=0 qk = 1 + q + q2 + ....+ qn?1 (? = n ?
