 +In $M$, $\alpha$ is an action profile (action profiles are not illustrated if they are not important).
 +Suppose $012\models \langle A \rangle p$. In the transformed model, we label state $012$ by $p_\xi$.

 ==== Example 2 ==== ==== Example 2 ====
 +In $M$, $\xi=\langle A \rangle G a$. We have $012^+ \models \xi$. In the transformed model, we have an infinite number of states, each one corresponding to a history $012..2$. They are all labelled with $p_\xi$.
