Dimension of totally reflexive modules
For that matter, if $R$ is a domain and $M^{**}\neq 0$, then $\dim M=\dim R$. |

Vanishing theorems for pluri-canonical bundle
And if you look at the proof in the cited paper, the author first comments that this is a special case of Kollár's vanishing and immediately goes to saying that he will only prove it for the case $\dim X=\dim Y$. I think he called it GR vanishing mistakenly. It's not a big deal to me, but Kollár's vanishing is a lot harder than GR vanishing, so he should get the credit for it. |

Could you tell me the definition of a simplicial cone? Thanks |

Degree and quasi projective family
Why can't you take the closure $\bar V$ of V in $\mathbb P^n\times \mathbb P^m$ and apply your argument in the projective case? It seems to me that $\deg V_p\leq \deg (\bar V)_p$, so this should be OK. |

An affine singular surface
Indeed, I hesitated writing that about being "more familiar" as it surely depends on one's point of view. Also, at the end it is the same thing. From the fact that the exceptional curve is a smooth rational curve with self-intersection $-n$ it follows easily that the resolution of the projectivized cone is actually $\mathbb F_n$. |

Kawamata-Log-Terminal pairs
@ggelli: If $\tilde\Delta\subset X$ is a smooth Cartier divisor, then $(X,\varepsilon\tilde\Delta)$ is klt for any $1>\varepsilon>0$ essentially by the argument you're providing. On the other hand, if you want to change or refine your question, you should do it by editing the question and not by posting a comment to an answer. |
