-adic superspaces and Frobenius
arXiv:math/0605310
Abstract
The notion of a -adic superspace is introduced and used to give a transparent construction of the Frobenius map on -adic cohomology of a smooth projective variety over $\zp$ (the ring of -adic integers), as well as an alternative construction of the crystalline cohomology of a smooth projective variety over $\fp$ (finite field with elements).
