| Dec 3, 2010 at 8:45 | comment | added | Ben Webster♦ | By the way, the only varieties you'll ever get are the usual projs of taking the graded pieces for multiples of a single generic vector in your monoid (maybe after saturation). You might also want to look into geometric invariant theory. | |

| Dec 3, 2010 at 8:31 | comment | added | Ben Webster♦ | This is called "multi-proj" for submonoids of Z^n and is annoyingly hard to google due to google thinking you really meant "multi-project". Look in Miller and Sturmfels. | |

| Dec 3, 2010 at 7:39 | comment | added | Anton Geraschenko | What does "sharp" mean? That is has an identity and embeds into its Grothendieck group? Googling produces many instances of the phrase "sharp monoid", but not a definition. | |
