Topic: How to write repeated tensor products
Jason Rute (Aug 18 2024 at 01:32):
This PA.SX question is about how to naturally write things like . While I could give some answer using List
and foldr
/foldl
, I assume there might be a more canonical solution in this case.

We have docs#PiTensorProduct

I see now that the question is about tensor products in a monoidal category, and there is indeed no canonical way yet. The default would be to associate to the right, similarly to how products work at the type level.
