| Feb 15, 2013 at 22:45 | comment | added | Martin Brandenburg | @Mariano: One uses that the underlying space of the scheme-theoretic fiber is the set-theoretic fiber. When you try to do it algebraically, without knowing anything about fibers, one has to check that one really can recover the prime ideals from the corresponding prime ideals in $\kappa[X]$, where $\kappa$ is a residue field. Again this gets clumsy. See here: math.stackexchange.com/questions/174595/…. | |
