Spahn Witt vectors (Rev #1)

Prüfer group

In the Prüfer $p$-group every element has precisely $p$ $p$-th roots.

It is unique up to isomorphism.

Tate module

$End(Pr$

Prüfer $p$-group

$p$-group

Sylow $p$-subgroup of $Q/Z$ consisting of those elements whose order is a power of $p$: $Z(p^\infty)=Z[1/p]/Z$

Frobenius automorphism

(relative Frobenius lifts some problems with the plain frobenius of shemes)

Witt vectors

Is it right to say that this is a cohomological invariant?
