Movable Divisors
Yes, it seems to be the right definition. In my mind, the divisor $D$ was moving but one part was not. But the correct definition is certainly the one that you give. So we still do not have an example (if it exists). |

Movable Divisors
Good point. In this case, I do not know if such example really exists. |

A question od being algebraic stable for birational map
What kind of characterization are you looking for? You gave the definition. Equivalently, you can ask that $(f^k)^*=(f^*)^k$ for $k>0$, where $*$ means the action on $NS$. But the definition you give is much easier to check. |
