因みに、” the familiar Galois module “Z＾(1)””とか合ったので下記を引用しておきます

§ 2.6. Positive characteristic model for mono-anabelian transport
In this example, Galois
groups, or ´etale fundamental groups, in some sense play the role that is played
by tangent bundles in the classical theory - a situation that is reminiscent of the
approach of the [scheme-theoretic] Hodge-Arakelov theory of [HASurI], [HASurII],
which is briefly reviewed in §2.14 below. One notion of central importance in this
example - and indeed throughout inter-universal Teichm¨uller theory! - is the notion
of a cyclotome, a term which is used to refer to an isomorphic copy of some quotient
[by a closed submodule] of the familiar Galois module “Z＾(1)”, i.e., the “Tate twist” of
the trivial Galois module “Z＾”, or, alternatively, the rank one free Z＾-module equipped
with the action determined by the cyclotomic character. Also, if p is a prime number,
then we shall write Z＾=p for the quotient Z＾/Zp.
