Reference request: Samuel’s multiplicity and degree Hi Oleg, the comment of Steven Landsburg on this question: mathoverflow.net/questions/129673/… implies that Samuel's book should have a reference to at least the first question of yours. |

Contracting a curve of negative self-intersection on a surface Hi Philip, this article (of mine) gives a necessary and sufficient criterion for algebraicity in a special case: arxiv.org/abs/1301.0126 PS: I myself am interested in your Question 1, and I don't know of any other reference other than Grauert's original article, which is in German and therefore I can't read :( |

A question on counting non-leading monomials Is $a_{I,m}$ by definition $\lim_{k\to \infty} \sigma_{I,m}(k)/kh_I(k)$? If not, what is it? |

Normality condition on graded algebra Hi Isac, A look at Chapter 5 of people.reed.edu/~iswanson/book/SwansonHuneke.pdf might help. |

Contracting rational curves on surfaces and getting something non-algebraic @Jason: OK, I admit it wasn't such a good choice of words :) Would you prefer if I change "something non-algebraic" to "non-algebraic surfaces"? |

Contracting rational curves on surfaces and getting something non-algebraic @Angelo: Thanks! But I knew of these (perhaps should have mentioned them in the question) and they do not contain (and as far as I can see, do not shed any light on the construction of) any such examples. |

$d$ points on a curve which are in the base locus of a pencil of planes Hi Francesco, the projection from a generic $p \in L$ may not be birational! The correct answer seems to be that either $L$ is a component of $C$, or there are hyperplanes $H_1, \ldots, H_m$ containing $L$ and curves $C_j \subseteq H_j$ of degree $d_j$ such that $1 \leq m \leq n$, $d_1 + \cdots d_m = d$ and $C = C_1 \cup \cdots \cup C_m$. |

What are some examples of colorful language in serious mathematics papers? Oops! I just voted up and destroyed the magic of 27! I am really sorry, now if I downvote it becomes 26! |
