I recently learned about the poincare-birkhoff fixed point theorem, and was wondering if there is a simple example of an area-preserving (or some weaker assumptions) twist map on the annulus which has exactly two fixed points.

Plus, I am looking for a natural class of examples of such maps that has only a few fixed points.
