| Apr 1, 2010 at 21:53 | comment | added | Soroosh | Regarding N being the smallest N that keeps track of the degeneracy locus, won't that calculate the radical of the discriminant? That seems different from the conductor, which distinguishes between places of additive reduction and places of multiplicative reduction. I think the correct way of approaching this is to think of conductor as a representation theory invariant, while the natural geometric invariant is the discriminant. These two however are related via Ogg's formula (or I guess Ogg-Saito's formula). | |
