Finitely many singular points of an irreducible polynomial
This is not a research level question. Please, consider asking on math.SE. |

Reference needed: Homology of the blow-up
Do you put any restrictions on $V$? |

Dimension of a commuting nilpotent variety
I'd say that this is a no so trivial question. Namely, if you omit the "commute with $A$" condition, you get the variety of commuting nilpotent matrices. Its dimension is $n^2-1$, which is not obvious (see "The Variety of Pairs of Commuting Nilpotent Matrices is Irreducible" by Volodia Baranovsky). |

For what varieties do we have results on the category of singularities?
You'd better call it "(triangulated) category of singularities". Not to confuse with smoothness. |

Does quasi-projective imply quasi-compact (in the Zariski topology)?
@QiaochuYuan sure, that's actually a criterion. Thank you for the term though, have never heard of this one. |

@HugoChapdelaine no problem, happens to all of us |

Grothendieck group of intersection of quadrics
I personally don't see any problem here. As far as I'm concerned, an intersection of two even-dimensional quadrics has odd dimension. |

Grothendieck group of intersection of quadrics
The decomposition you mention is due to Bondal and Orlov, not just Orlov. |
