The basic geometry of Witt vectors, I: The affine case

Borger, James


We give a concrete description of the category of ├ętale algebras over the ring of Witt vectors of a given finite length with entries in an arbitrary ring. We do this not only for the classical p-typical and big Witt vector functors but also for certain a
