The -adic Tate conjecture for crystalline cohomology
The -adic Tate conjecture for crystalline cohomology
Let be a smooth projective variety over the finite field of characteristic , with . Let be the ring of -typical Witt vectors, let , and let . Let denote crystalline Frobenius. -adic Tate conjecture. The cycle class map
with values in the -vector subspace fixed by is surjective. This is the crystalline formulation of the Tate conjecture over finite fields and remains open in general.
