Proposition: Convergence Behaviour of Absolutely Convergent Series

  1. Every absolutely convergent series is also convergent (in the usual sense).
  2. The converse does not hold: there are some convergent series, which are not absolutely convergent.

In that sense, the absolute convergence is a stronger property than the convergence.
