Extract

Singer [10] defined a series Σxk in a Banach space X to be weakly p-unconditionally Cauchy if and only if Σλkxk converges in X for all λ∊lp, where 1 < p < ∞. For Banach spaces containing no subspace isomorphic to c0 Singer characterized such series as those for which

where 1/p + 1/q = 1 and X′ is the dual space of X.
