Abstract: Let $ N(X)$ be the set $ \{ F\varepsilon X''$: there exists a weakly unconditionally converging series $ \Sigma {x_n}$ in $ X$ such that $ F = \sigma (X'',X') - {\lim _n}\Sigma _{i = 1}^nJ{x_i}\} $. Representation theorems for the unconditionally converging operators (map weakly unconditionally converging series into unconditionally converging series) are developed by using the $ \sigma (X',N(X))$ topology of $ X'$.
