The kind of fibrations I am interested in are when $X$ is a smooth Calabi-Yau threefold and $Y$ is $\mathbb{P}^3$. I don't care about the complex structure of $X$, so I am looking for a generic member of its complex moduli space. If there are theorems for those particular type of fibrations, I would appreciate if you recall that. | |
