Arithmetic geometry (especially Shimura varieties and abelian varieties).

comment Can algebraic varieties be rigidified by finite sets of points?
Yes, another nice example (you need to choose Fq large enough so that the variety, the points, and the automorphism are defined over it). So I was wrong in my claim for abelian varieties --- the result I was thinking of applies to polarized abelian varieties.
