Definition: Convergent Complex Series

A complex series \(\sum_{k=0}^\infty x_k\) is called convergent, if the complex sequence \((s_n)_{n\in\mathbb N}\) of partial sums \[s_n:=\sum_{k=0}^n x_k,\quad\quad n\in\mathbb N\] is a convergent complex sequence. For convergent complex series, the notation

\[\sum_{k=0}^\infty x_k\]

can, depending on the context, denote two things:

1. the convergent real series itself or
2. the convergent real series itself or
