Lifting a birational map of $X/G$ to a birational map of $X$?
Thank you for the answer, Tom. I now think my claim is positive although I cannot prove it. I will post something once I am convinced with my idea. |

When does $Aut(X)=Bir(X)$ hold?
I see. Thank you for clarifying the point. |

Thank you for the useful comments. Do you know anything about Calabi-Yau case? K3 surface is minimal and thus the equality holds (thanks to Christian'sanswer below). What about dimension 3 case? |

Sorry for a (potentially) stupid question, but could you give me an example of compact $X$ such that $Bir(X)\ne Bim(X)$? |

Thank you for the example, Piotr. Do you know how to prove the fact about Abelian varieties? |

Thank you for the answer, Sasha. Logarithm part now makes sense to me. But I am not totally convinced by the phase part yet. I will think about it more. |

@Angelo It seems you can type the explicit equation. I would appreciate your edit. |

I cannot write down the natural metric on this post. THe equation does not appear well. So I put a link to a paper by Bridgeland. |
