A Note on Generalized Multiplier Spaces and Applications to $\alpha AB$-, $\beta AB$-, $\gamma AB$- and $NAB$-duals
Abstract
\[
M(X,Y)=\{a=(a_k)\in \omega \mid ax\in Y \mbox{, for all }x\in X\}
\]
where $\omega$ denotes the space of all complex-valued sequences and $X$ and $Y$ are sequence spaces. Specially, putting $Y=cs$, where $cs$ is the set of convergent series, the multiplier space becomes the $\beta$-dual of $X$. We will present some generalized results related to $X^{\beta}$ and extend some of existing. Finally, we will illustrate these generalizations with some examples and applications.
