Topic: Propositions as types, BHK and Computational trilogy


view this post on Zulip Jencel Panic (Aug 15 2024 at 07:10):

Are there any significant differences between the idea of Propositions as types and of computational trilogy AKA trinitarianism, except for the fact that the latter also includes categories and spaces?

Judging from the table on the nlab page of computational trilogy, the answer is no, the first header goes:

Also, there are other related terms such as Curry-Howard correspondence (there is also Curry-Howard-Lambek) and the BHK interpretation.

Ah, now I see that the above nlab has an aswer to my question:

computational trinitarianism = propositions as types + programs as proofs + relation type theory/category theory

Still, it's interesting to see people's perspective.

Check out the variant Propositions as some types. This is still part of the trinitarian picture.
