May 9, 2012 at 16:53 comment added Marc Palm Glad that you found my solution helpful, but Keith Conrad's reference Goldman and Sah is something I was not aware of.
May 9, 2012 at 16:40 comment added Konrad Voelkel @Mrc Plm: Thank you! So the solution of my headache was to see the infinitely many conditions as a colimit over finitely many conditions. That could work in other settings, too. @Ryan Reich: Thanks for the suggestion, I like Tate's symbol.

May 7, 2012 at 6:45 comment added Marc Palm \mathrlap{coprod}\prod should do, see e.g. here...
May 7, 2012 at 2:33 comment added Chandan Singh Dalawat ... short of writing a macro to superpose $\prod$ and $\coprod$.
May 7, 2012 at 2:30 comment added Chandan Singh Dalawat I like that symbol for the restricted product. How do you code for it in TeX or LateX ?
May 6, 2012 at 19:07 comment added Ryan Reich I've seen Tate write the restricted product as $\rlap{\prod}\coprod$; i.e. a product combined with a coproduct, just as you decsribe it.
