Idea
The constant map¶ from A
to B
at an element b : B
is the function x ↦ b
mapping every element x : A
to the given element
b : B
. In common type theoretic notation, the constant map at b
is the
function
λ x → b.
Definition
const : {l1 l2 : Level} (A : UU l1) {B : UU l2} → B → A → B const A b x = b
