Thank you very much. May I ask for some more detail explanation of it? |

inverse image in the blowup
Thank you very much. If I understand correctly, everything should work in a nice way if $Z_1$ and $Z_2$ are both integral. Am I right? |

hyperelliptic stable genus four curve
Yeah, this is what I did for a couple of cases. And that's how I made such an expectation. |

hyperelliptic stable genus four curve
In fact, on any smooth genus four curve, a degree three line bundle has at most two linearly independent global sections. So $h^0=2$ and $ h^0\geq 2$ make no difference. |

normal bundle of hyperelliptic locus
For smooth curves, this is not hard. What's tricky is the singular part... |
