Milne’s rationality conjecture and algebraic specialization

Proves Milne's rationality conjecture for abelian varieties over Q‾\overline{\mathbb Q} with good reduction: specialized Hodge classes pair rationally with complementary divisor products, independently of cohomology theory. Together with result 032, every specialized Hodge class is represented by a single rational algebraic cycle simultaneously in all prime-to-p and crystalline realizations, for every residue characteristic p.
