We introduce double series and we shall give the definition of their convergence and divergence. Then we study the relationship between double and iterated series, The theory of double series is intimately related to the theory of double sequences. To each double sequence z: N×N −→ C, there corresponds three important sums; namely:
And we give a sufficient condition for equality of iterated series.
