Query: Notes on absolute Hodge classes   We survey the theory of absolute Hodge classes. The notes include a full
proof of Deligne's theorem on absolute Hodge classes on abelian varieties as
well as a discussion of other topics, such as the field of definition of Hodge
loci and the Kuga-Satake construction.
