β-Dual Dari Ruang Barisan (N̅,Δλ)<sub> ∞</sub>, (N̅,Δλ), Dan (N̅,Δλ)<sub>O</sub>
Abstract
Sequence spaces is one of interesting topic of analysis research. Some of that are convergent and bounded sequence. In this paper we define some releated BK spaces (N̅,Δλ)<sub> ∞</sub>, (N̅,Δλ), dan (N̅,Δλ)<sub>O</sub> some characteristics releated to them. Moreover we determine their β-dual.
