    Hm, ever since I put those pdf-links into IUTT the server that hosts them seems to be down. Or I am being stupid. I could swear I did open the pdf behind these links this morning. But now I just get a server error when I try to. Is this just me? Do I have some typo in the URLs? ?!?

    Ah, never mind. Now I can reach them again. Or can I? Hm, number III) I get now. But number IV) still not.

    I found it slow. I called up IUTT III, got it, and changed the III to IV in the URL It then came up without problem. Back on the IUTT entry it then worked. I will clear my Firefox cache and try again. (Edit: It seems to work for me now.)

    There are periods when the site with Mochizuki’s web pages is not responsive and the times when everything is OK.

    Regarding the model-theoretic content of the page cf. my remarks in the comment 37 in the parallel discussion.

    Since you seem to be following this, is anything more clear about the connection with universe enlargement available?

    @spitters, not that I could see in this, nor in another recent Mochizuki document answering questions put to him about the programme.

    I never understood why universe enlargement should be such a big deal. Does it amount to anything more than the book-keeping of ’typical ambiguity’ or ’universe polymorphism’, as Mike explains?

    …as long as you aren’t deliberately perverse, you won’t usually have to worry about universe inconsistencies… in non-formalized mathematics, we are always free to drop into explicit universe polymorphism if it ever seems necessary for clarity. But most of the time, it isn’t.

    Doesn’t sound like a powerful principle to find out new things in number theory.

    Given the name “Inter Universal”, apparently Mochizuki thinks it is important.

    @spitters his appendix to IUTT IV that show why he uses this name is not referred to in a substantial way a single time in the four papers. Also, his use of set theory is very odd, so I think of that appendix as a hack from someone not au fait with foundational issues.
