Nuprl Lemma : hdf-once_wf
∀[A,B:Type]. ∀[X:hdataflow(A;B)]. (hdf-once(X) ∈ hdataflow(A;B))
Proof
Definitions occuring in Statement :
hdf-once: hdf-once(X),
hdataflow: hdataflow(A;B),
uall: ∀[x:A]. B[x],
member: t ∈ T,
universe: Type
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
hdf-once: hdf-once(X),
so_lambda: λ2x.t[x],
so_apply: x[s],
so_lambda: λ2x y.t[x; y],
all: ∀x:A. B[x],
so_apply: x[s1;s2]
Latex:
\mforall{}[A,B:Type]. \mforall{}[X:hdataflow(A;B)]. (hdf-once(X) \mmember{} hdataflow(A;B))
