Hi,


Thanks for your responses, and apologies for the delay in mine.


Indeed, a deep embedding is what I'm after - thank you for providing the phrase to express what I was after. And thank you both for attaching excerpts of your code. It's a little surprising to me that there isn't a standard or general library available, as opposed to individual's tailored formulation. 


Anyway! Thanks again for your help.


All the best,
Caitlin

I needed a deep embedding of first-order arithmetic some time ago. In
the end I wrote my own. See in particular the file
"heytingarithmetic.v" at

https://github.com/anderslundstedt/pca-realizability

I tailored the embedding quite heavily to my own needs, but perhaps
the definitions can be adapted for a more general setting.
