| Jan 4, 2011 at 19:24 | comment | added | Pete L. Clark | I agree with Emerton: this question is certainly of research level. The problem is that I think it is easy to give a three word answer --"generalized elliptic curves" -- but to do much better, I think one has to point to rather long, intricate papers, as I have in my answer below. | |

| Jan 4, 2011 at 19:14 | comment | added | Emerton | I think this is a perfectly good question for MO. As Barinder writes, the cusps classify generalized elliptic curves with level structure. This is worked out in Deligne--Rapoport (and I don't know of any other reference, although a more recent one may exist). | |
| Jan 4, 2011 at 19:08 | comment | added | Barinder Banwait | They correspond to so-called "generalised elliptic curves"; I think the standard reference is Deligne-Rapoport. | |
