Topic: Countable product type

What's the notation for a product of types likevariables (α β : Type u) (p: α × β)
but with countable elements instead of two elements?

It's dependent functions from nat
Adam Topaz (Aug 24 2020 at 23:04):
I.e. given T : nat -> Type*
, you could do this \Pi (n : nat), T n
.

T is the analogue of your choice of alpha and beta, and the Pi type is the analogue of the product
