    The page on inductive-inductive types refers to dialgebras without specifying them. Having a short page as some sort of reference is helpful.

    The general style of the nLab is to have concepts in the singular, so I’m removing the pluralisation of the page.

    Thanks!

  4. I added references to some relatively recent work on dialgebras advancing the study of their applications to program semantics (in particular using quotient objects instead of final objects).

    Mention that dialgebras were originally introduced by Lambek as “subequalizers”.

    In the recent nnLab discussions on quantum modal logic, wasn’t the need for some construction like a dialgebra, F(x)→G(x)F(x) \to G(x), expressed?

    Or was it perhaps to what would be the morphisms in the Kleisli set-up, F(x)→G(y)F(x) \to G(y)? Perhaps a ’diKleisli morphism’?

    I ended up not seeming to have use for it after all, but a couple (literally) of references on the “two-sided Kleisli category” are since being referenced there.

    I haven’t thought about relating this to di-morphisms, but it seems suggestive.
