About normalization
I think probably googling it will give you some references. The classic reference is Greco-Traverso. There was a recent survey (from an algebraic perspective) by Marie Vitulli. |

About normalization
There is also the related notion of seminormality. $Y$ (a variety over $\mathbb{C}$) is called seminormal if every map of varieties $X \to Y$ which is finite and bijective is an isomorphism (and hence birational as well). Normal implies seminormal. |

embedding dimension of normal surface singularity
What are you asking, what can't you understand? Where exactly are you taking this from? |

On the number of irreducible components of an exceptional divisor
My recollection is that even for several lines meeting transversally (pairwise), when you blow them up you can get all sorts of weird components over the center. Have you tried any examples? |

On the number of irreducible components of an exceptional divisor
Are you always blowing up the set $Z$ with the reduced scheme structure, or are you allowing other scheme structures... If the former I'm not sure there is much that can be said. |
