math_jin氏も、下記フェセンコ氏の
文書の持つインパクトが分かっていないよう

数学に詳しくないのだろうかね
日本の数学徒(プロ数学者を含む)なら、「IUTは遠アーベル幾何から派生した新たな類体論」と言われて、驚かない人はいないだろうにね

P16
Here are some relations between the three generalisations of CFT and their further developments:

2dLC?−− 2dAAG−−− IUT
 l   /  |     |
 l  /    |     |
 l/      |     |
 LC    2dCFT  anabelian geometry
 \      |     /
   \     |   /
    \   |  /
        CFT
注)記号:
Class Field Theory (CFT), Langlands correspondences (LC), 2dAAG = 2d adelic analysis and geometry, two-dimensional (2d)
(P8 "These generalisations use fundamental groups: the etale fundamental group in anabelian geometry, representations of the etale fundamental group (thus, forgetting something very essential about the full fundamental group) in Langlands correspondences and the (abelian) motivic A1 fundamental group (i.e. Milnor K2) in two-dimensional (2d) higher class field theory.")
Problem 7. Find more direct relations between the generalisations of CFT. Use them to produce a single unified generalisation of CFT.23
