Abstract :In this paper, we introduce some new multiplier sequence spaces by using sequences in a normed space $X$ and matrix domain of Ces\`aro summability method in $\ell_\infty$ and $c_0$. Then we obtain the characterizations of completeness and barrelledness of normed space $X$ through its weakly and weakly* unconditionally Cauchy series.
Keywords : Mulpilier spaces, weakly unconditionally Cauchy series, completeness, Cesáro sequence spaces, barrelledness
