On the Space of Sequences of p-Bounded Variation and Related Matrix Mappings
The difference sequence spaces ℓ∞(△), c(△), and c₀(△) were studied by Kızmaz. The main purpose of the present paper is to introduce the space bv p consisting of all sequences whose differences are in the space ℓp , and to fill up the gap in the existing literature. Moreover, it is proved that the sp...

The main purpose of the present paper is to introduce the space bv p consisting of all sequences whose differences are in the space ℓp , and to fill up the gap in the existing literature. Moreover, it is proved that the space bv p is the BK-space including the space ℓ p . We also show that the spaces bvp and ℓp are linearly isomorphic for 1 ≤ p ≤ ∞. Furthermore, the basis and the α-, β-, and γ-duals of the space bvp are determined and some inclusion relations are given. The last section of the paper is devoted to theorems on the characterization of the matrix classes (bvp : ℓ∞), (bv∞ : ℓp ), and (bvp : ℓ1), and the characterizations of some other matrix classes are obtained by means of a suitable relation. |
