Appendix to ``Deligne's integrality theorem in unequal characteristic and rational points over finite fields'' by Hélène Esnault

arXiv:math/0409286

Abstract

One extends P. Deligne's notion of integrality over a finite field for a $ℓ$ -adic sheaf on a scheme of finite type over a local field with finite residue field. One shows that this integrality notion is preserved by $R f_{!}$ , as it is over a finite field after P. Deligne.
