| Jul 12, 2021 at 19:00 | comment | added | Student85 | Sorry, this question is amazing for me. In the case when $Bl_{Z}(X)$ is non singular, what can happen with $E= \pi^{-1}(Z)$? This is a divisor contained in $Bl_{Z}(X)$. This is smooth (non singular) or singular? When it is singular, what type of singularities (dimension) ? | |
