Definition: Bounded Complex Sequences

Let \((a_n)_{n\in\mathbb N}\) be a complex sequence. Since the absolute value of a complex number is a real number, we can compare it to other real number using the order relation for real numbers "\(\le\)".

We call the complex sequence \((a_n)_{n\in\mathbb N}\) bounded, if there is a positive real number \(B\) with \(|a_n|\le B\) for all \(n\in\mathbb N\).
