Mutually Alien Copies に関連しそうなところを、下記に引用すると
1）N ・ h “=〜” h N be a fixed natural number > 1
2）qN “=〜” q
3）“alien” is that of its original Latin root, i.e., a sense of abstract, tautological “otherness”.

Introduction
Let N be a fixed natural number > 1. Then the issue of bounding a given nonnegative real number h ∈ R?0 may be understood as the issue of showing that N ・ h is
roughly equal to h, i.e.,
N ・ h “=〜” h
[cf. §2.3, §2.4]. When h is the height of an elliptic curve over a number field, this
issue may be understood as the issue of showing that the height of the [in fact, in most
cases, fictional!] “elliptic curve” whose q-parameters are the N-th powers “qN ” of the
q-parameters “q” of the given elliptic curve is roughly equal to the height of the
given elliptic curve, i.e., that, at least from the point of view of [global] heights,
qN “=〜” q
[cf. §2.3, §2.4].

つづき

In order to verify the approximate relation qN “=〜” q, one begins by introducing
two distinct - i.e., two “mutually alien” - copies of the conventional scheme
theory surrounding the given initial Θ-data. Here, the intended sense of the descriptive
“alien” is that of its original Latin root, i.e., a sense of
abstract, tautological “otherness”.

These two mutually alien copies of conventional scheme theory are glued together
- by considering relatively weak underlying structures of the respective conventional
scheme theories such as multiplicative monoids and profinite groups - in such a
way that the “qN ” in one copy of scheme theory is identified with the “q” in the other
copy of scheme theory. This gluing is referred to as the Θ-link. Thus, the “qN ” on the
left-hand side of the Θ-link is glued to the “q” on the right-hand side of the Θ-link, i.e.,
qNLHS “=” qRHS
[cf. §3.3, (vii), for more details]. Here, “N” is in fact taken not to be a fixed natural
number, but rather a sort of symmetrized average over the values j2, where j = 1,...,l*, and we write l* def = (l ? 1)/2. Thus, the left-hand side of the above display
{qj2LHS}j
bears a striking formal resemblance to the Gaussian distribution. One then verifies
the desired approximate relation qN “=〜” q by computing
{qj2LHS}j
- not in terms of qLHS [which is immediate from the definitions!], but rather - in
terms of [the scheme theory surrounding]
qRHS
[which is a highly nontrivial matter!].

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

(引用開始)
P17
§ 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.

[L1] Arithmetic deformation theory via arithmetic fundamental groups and nonarchimedean theta functions, notes on the work of Shinichi Mochizuki, Europ. J. Math. (2015) 1:405?440
P15
Monoid-theoretic structures are of essential importance in IUT, since they allow one to construct various gluing isomorphisms.
The use of Galois and arithmetic fundamental groups gives rise to canonical splittings objects arising from such gluing isomorphisms by applying various tautological Galois-equivariance properties of such gluing isomorphisms.
The computation of the theta-link can be viewed as a sort of passage from monoid-theoretic data to such
canonical splittings involving arithmetic fundamental groups, by applying generalised Kummer theory, together with various multiradial algorithms which make essential use of mono-anabelian geometry.

証明したいディオファントス不等式に定理3.11を解釈しなおすと、系3.12が導かれるとある。

Mochizuki, Shinichi Inter-universal Teichmüller theory IV: Log-volume computations and set-theoretic foundations. Publ. Res. Inst. Math. Sci. 57 (2021), no. [1-2], 627–723

Theorem 3.11 in Part III is somehow reinterpreted in Corollary 3.12 of the same paper in a way that relates to the kind of diophantine inequalities one wishes to prove. One constructs certain arithmetic line bundles of interest within each theatre, a theta version and a q-version (which at the places of bad reduction arises essentially from the q-parameter of the corresponding Tate curve), which give rise to certain theta and q-objects in certain (products of) Frobenioids: the theta and q-pilots. By construction the theta pilot maps to the q-pilot via the horizontal link in the log-theta lattice. One can then proceed and compare the log-volumes of the images of these two objects in the relevant objects constructed via the multiradial algorithm in Theorem 3.11.

＞やはり、IUT論文を”査読”したのはSaidi氏のようですね

そのような自己レスの行為は、よほど厚顔無恥な者でない限りやらない。
自分が査読した論文の書評を書くことは、いくら何でも有り得ない　ｗｗ
