Degenerations and limit Frobenius structures in rigid cohomology
We introduce a 'limiting Frobenius structure' attached to any degeneration of projective varieties over a finite field of characteristic p which satisfies a p-adic lifting assumption. Our limiting Frobenius structure is shown to be e ectively computable in an appropriate sense for a degene...
