Nuprl Lemma : unsquashed-seq-cont_wf
∀[T:Type]. ∀[F:(ℕ ⟶ T) ⟶ ℕ]. (unsquashed-seq-cont(T;F) ∈ ℙ)
Proof
Definitions occuring in Statement :
unsquashed-seq-cont: unsquashed-seq-cont(T;F),
nat: ℕ,
uall: ∀[x:A]. B[x],
prop: ℙ,
member: t ∈ T,
function: x:A ⟶ B[x],
universe: Type
Definitions unfolded in proof :
exists: ∃x:A. B[x],
all: ∀x:A. B[x],
not: ¬A,
false: False,
less_than': less_than'(a;b),
and: P ∧ Q,
le: A ≤ B,
uimplies: b supposing a,
so_apply: x[s],
subtype_rel: A ⊆r B,
nat: ℕ,
prop: ℙ,
implies: P ⇒ Q,
so_lambda: λ2x.t[x],
unsquashed-seq-cont: unsquashed-seq-cont(T;F),
member: t ∈ T,
uall: ∀[x:A]. B[x]
