Applications of Orlicz–Pettis theorem in vector valued multiplier spaces of generalized weighted mean fractional difference operators
Abstract In this study, we deal with some new vector valued multiplier spaces S G h ( ∑ k z k ) $S_{G_{h}}(\sum_{k}z_{k})$ and S w G h ( ∑ k z k ) $S_{wG_{h}}(\sum_{k}z_{k})$ related with ∑ k z k $\sum_{k}z_{k}$ in a normed space Y. Further, we obtain the completeness of these spaces via weakly unco...

Abstract In this study, we deal with some new vector valued multiplier spaces S G h ( ∑ k z k ) $S_{G_{h}}(\sum_{k}z_{k})$ and S w G h ( ∑ k z k ) $S_{wG_{h}}(\sum_{k}z_{k})$ related with ∑ k z k $\sum_{k}z_{k}$ in a normed space Y. Further, we obtain the completeness of these spaces via weakly unconditionally Cauchy series in Y and Y ∗ $Y^{*}$ . Moreover, we show that if ∑ k z k $\sum_{k}z_{k}$ is unconditionally Cauchy in Y, then the multiplier spaces of G h $G_{h}$ -almost convergence and weakly G h − $G_{h}-$ almost convergence are identical. Finally, some applications of the Orlicz–Pettis theorem with the newly formed sequence spaces and unconditionally Cauchy series ∑ k z k $\sum_{k}z_{k}$ in Y are given. |
