Secondary fans and Stanley Reisner ideals
It's apparently a bug in chrome for Linux. Do you happen to know of an algorithm to explicitly compute all coherent triangulations of a set $S$? |

Secondary fans and Stanley Reisner ideals
Thanks David! The codimension one problem has been throwing me for awhile. Something's wrong with the display of your first equation though; it should be $$\tilde{f}(w) = \max \{ \sum a_i f(s_i) : \ \sum a_i s_i = w,\ a_i \geq 0 \}.$$ |

Constructing affine hypersurfaces with one singularity
@mdeland: I understand that they are equivalent. I don't understand how this answers my question; you've just rephrased it to "what are conditions on $S$ and/or $H$ such that the weighted projective space is smooth". Having coprime weights that divide the degree is not enough: I can assign degree 2 to $x$ and 1 to $y$ in example 1, and $2|6$, but the singular locus of $x^3$ is not the origin. |

@mdeland; I want to know when the affine hypersurface has such a singularity. I hope I made that clear this time in my question. |
