Subject: [HoTT] Semantics of QIITs ?
Date: Thu, 16 May 2019 16:57:23 +0200
Message-ID: <CAOoPQuQBwyvbY_f3qNZOgEB7nxQHGUigqXjNhbDmCvB3xnVaOw@mail.gmail.com> (raw)

What is the status of the semantics of quotient inductive inductive types?
Looking at the literature there's some progress on reducing QIITs to
simpler constructions, but this does not seem to have led to a
convenient semantic result.
E.g. QIITs do not seem to be treated in the work by Lumdaine and Shulman.


Do we know that the prototypical QIITs from the book (e.g. Cauchy
reals) are supported in the usual models of HoTT?
