Aug 13, 2014 at 11:45 | comment | added | Yusuf Mustopa | I figured that this might be the case. You are still okay if $y$ is in the smooth locus of the underlying reduced scheme $B_{red}.$ However, you may want to edit the question to emphasize your interest in the branch point case. | |
Aug 13, 2014 at 11:43 | comment | added | Hans | Thank you. But in fact, the case where $y$ is in the branch locus is the case where I am interested in. | |
Aug 13, 2014 at 11:37 | comment | added | Yusuf Mustopa | Is $y \in Y$ allowed to be in the branch divisor $B$ of $f$? If not, 1 and 3 can be settled by taking $C$ to be a complete intersection of sufficiently ample divisors on $Y$ such that $C$ contains $y$ and intersects $B$ transversally (this follows from Bertini). | |
