Andrea Vezzosi f7f8953a42 Voe: Use the isomorphism directly for better computation 2018-03-15 13:39:42 +00:00
Frederik Hanghøj Iversen 438978973d Construct isomorphism from equivalence
Using this somewhat round-about way of constructing an isomorphism from
an equivalence has made typechecking slower in some situations.

E.g. if you're constructing an equivalence from gradLemma and later use
that constructed equivalence to recover the isomorphism, then you
might as well have kept using those functions.

Frederik Hanghøj Iversen 41e2d02c8d [WIP] Prove voe §2.3
By Andrea

The reason you cannot use cong in [1] is that §2-fromMonad result type
depends on the input, you need a dependent version of cong:

cong-d : ∀ {ℓ} {A : Set ℓ} {ℓ'} {B : A → Set ℓ'} {x y : A}
               → (f : (x : A) → B x)
               → (eq : x ≡ y)
               → PathP (\ i → B (eq i)) (f x) (f y)
cong-d f p = λ i → f (p i)

I attach a modified Voevodsky.agda.

Notice that the definition of "t" is still highlighted in yellow,
that's because it being a homogeneous path depends on the exact
definition of lem, see the comment with the two definitional equality
constraints.
