    I have created an entry type of types. Wanted to collect some literature there, but ended up not finding too much…

    I found the entry type of types a bit lacking in information, when I needed to point to it (from the currently last comment of this G+ discussion). So I expanded just a little bit.

  3. type universe used more commonly in the article

    Something strange happening with this page: When trying to (re-)sumit it, the parser complains about strings of the form

    \ type

    (i.e. backslash followed by whitespace is causing the error, but all the occurrences are followed by type)

    What’s the intended syntax?

    (And how was this saved in the first place?!)

    It used to be that having a backslash and a whitespace a la “\ ” used to allow the parser to parse the combination of characters into a whitespace in math mode, but that stopped working on the nLab a few days ago for some reason. “\ ” still works on my local computer’s latex editor to produce whitespaces in math mode.

    I see, thanks for saying. I’ll bring this to the attention of the technical team.

    Christian Sattler has fixed it, already!

  10. Added a paragraph on “mixed” Tarski universes which contain both strict definitional equalities and weak type equivalences in the definition of Tarski universe.
