Nuprl Lemma : eclass0_local
∀[Info,B,C:Type]. ∀[X:EClass(B)].
∀f:Id ⟶ B ⟶ bag(C). (LocalClass(X) ⇒ LocalClass((f o X))) supposing valueall-type(C)
Proof
Definitions occuring in Statement :
eclass0: (f o X),
local-class: LocalClass(X),
eclass: EClass(A[eo; e]),
Id: Id,
valueall-type: valueall-type(T),
uimplies: b supposing a,
uall: ∀[x:A]. B[x],
all: ∀x:A. B[x],
implies: P ⇒ Q,
function: x:A ⟶ B[x],
universe: Type,
bag: bag(T)
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
uimplies: b supposing a,
member: t ∈ T,
valueall-type: valueall-type(T),
has-value: (a)↓,
prop: ℙ,
all: ∀x:A. B[x],
implies: P ⇒ Q,
so_lambda: λ2x y.t[x; y],
subtype_rel: A ⊆r B,
so_apply: x[s1;s2]
Latex:
\mforall{}[Info,B,C:Type]. \mforall{}[X:EClass(B)].
\mforall{}f:Id {}\mrightarrow{} B {}\mrightarrow{} bag(C). (LocalClass(X) {}\mRightarrow{} LocalClass((f o X))) supposing valueall-type(C)
