∀[A,B:CubicalSet]. (A ⟶ B ∈ 𝕌')
Proof
Definitions occuring in Statement :
cube-set-map: A ⟶ B,
cubical-set: CubicalSet,
uall: ∀[x:A]. B[x],
member: t ∈ T,
universe: Type
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
cube-set-map: A ⟶ B,
ext-eq: A ≡ B,
and: P ∧ Q,
subtype_rel: A ⊆r B
