"Introduction to the work of Baker and DeMarco"

We give an overview of the following result of Baker--DeMarco: if $\varphi,  \psi \in\mathbb{C}(z)$ have infinitely many preperiodic points in common, then all of their preperiodic points are the same. We discuss the connection between this complex analytic statement and non-archimedean Berkovich spaces.
