Dec 17, 2013 at 11:27 comment added naf As I said before, if you know a reference for arbitrary abelian varieties it should not be difficult to work out the statement for arbitrary varieties (except that some things that are known for abelian varieties are still conjectural for general varieties, e.g., 13.4? in Serre's article.)
Dec 17, 2013 at 11:16 comment added naf Sorry, I didn't have the article with me when I wrote the comment. The precise statement is 13.5?; however, you will probably have to read some of the earlier sections for this to mean anything.
Dec 16, 2013 at 23:35 comment added Qiaochu Yuan @ulrich: unfortunately my mathematical French is quite poor. Can you at least indicate which statement in that section I should be looking at?
Dec 16, 2013 at 4:26 comment added naf See, for example, the last section of the article by Serre in "Motives", PSMP 55, for a formulation for arbitrary motives.
Dec 15, 2013 at 22:08 comment added Qiaochu Yuan @eric: yes, it's called the Sato-Tate group in the literature. But again I've only seen discussion of curves and abelian varieties.
Dec 15, 2013 at 21:25 comment added eric As you probably know, even for elliptic curves the form of the conjecture depends on whether you have CM or not. I guess in general there will be some sort of Mumford-Tate group (that's where things like the cup product will come in) and the conjecture should say that Frobenii are equidistributed within the real points of that group.

Dec 15, 2013 at 20:04 comment added Qiaochu Yuan @ulrich: that's certainly plausible. Do you know a reference where a conjecture of this form is asserted? I was only able to find conjectures about abelian varieties and curves. What's expected for more general varieties?
Dec 15, 2013 at 5:46 comment added naf There is no significant difference between higher dimensional abelian varieties and hypersurfaces: replace $H^1$ of the abelian variety with the middle dimensional cohomology of the hypersurface.
