Mar 19, 2013 at 6:12 comment added Basic Does Borcherd product type consideration say something?
Mar 17, 2013 at 14:08 comment added Basic Yes, by non-trivial, I mean what Carnahan said and also to avoid oldforms. It seems that this might be a very rare phenomena. However, I do not know of any heuristics or conjectures even hinting this.
Mar 17, 2013 at 9:14 comment added user30035 If you'll allow me to use oldforms (which you probably won't) then there's a trick to ensure a common zero -- because of elementary considerations involving elliptic points (which can be dressed up via a "stacky" argument to look much more fancy), if the weight of a level 1 form (eigenform or not) is not 0 mod 4 then it will have a zero at i, and if it's not 0 mod 6 it will have a zero at $\rho$. However this trick goes away if you force the conductors to go to infinity, and in this case why would one expect common zeros at all?
Mar 17, 2013 at 7:16 comment added S. Carnahan By "nontrivial" do you mean the list should not admit a finite partition into subsets, each having a common multiple with a zero in the same place?
