Friends who were postdoc in Glasgow at the same time as me.
Japanese peers I’ve unilaterally decided are my close friends:
I am a former member of 都内数学科学生集合(TOSU), which is a group of students studying mathematics in the Tokyo metropolitan area, and served as its leader in 2014.
The following is the website of my friend, where you can find a large list of propositions equivalent to AC, and very detailed explanation of category theory with an amazing number of tikz diagrams! (But only in Japanese...)
I am a member of Baimon club (梅門クラブ), which is the alumni association of the baseball team in Fukushima High School.
