The weight-zero -adic invariant-cycles conjecture
The weight-zero -adic invariant-cycles conjecture
Let be regular, let be the sum of generalized -eigenspaces whose eigenvalues are roots of unity, and let be the étale specialization map. Weight-zero invariant-cycles conjecture. The map
is an isomorphism. The source records this as the portion of the preceding -adic invariant-cycles statement needed for its applications, namely the weight-zero (and smaller eigenvalue-one) part.
