Abstract:

The paper gives a unified treatment of the summation of certain iterated series of the form $ \sum_{n=1}^{\infty}\sum_{m=1}^{\infty}a_{n+m},$ where $ (a_{n})_{n\in \mathbb{N}}$ is a sequence of real numbers. We prove that, under certain conditions, the double iterated series equals the difference of two single series.
