Abstract:
In this paper we obtain two new characterizations of completeness of a normed space through the behaviour of its weakly unconditionally Cauchy series. We also prove that barrelledness of a normed space X can be characterized through the behaviour of its weakly-* unconditionally Cauchy series in X*.
Keywords: completeness; barrelledness; weakly unconditionally Cauchy series
