Nuprl Lemma : hdf-buffer_wf

∀[A,B:Type]. ∀[X:hdataflow(A;B ⟶ bag(B))]. ∀[bs:bag(B)].  hdf-buffer(X;bs) ∈ hdataflow(A;B) supposing valueall-type(B)


Proof




Definitions occuring in Statement :  hdf-buffer: hdf-buffer(X;bs),  hdataflow: hdataflow(A;B),  valueall-type: valueall-type(T),  uimplies: b supposing a,  uall: ∀[x:A]. B[x],  member: t ∈ T,  function: x:A ⟶ B[x],  universe: Type,  bag: bag(T)
Definitions unfolded in proof :  uall: ∀[x:A]. B[x],  member: t ∈ T,  uimplies: b supposing a,  hdf-buffer: hdf-buffer(X;bs),  all: ∀x:A. B[x],  implies: P ⇒ Q,  so_lambda: λ2x.t[x],  so_apply: x[s],  callbyvalueall: callbyvalueall,  has-value: (a)↓,  has-valueall: has-valueall(a),  bool: 𝔹,  unit: Unit,  it: ⋅,  btrue: tt,  ifthenelse: if b then t else f fi ,  bfalse: ff,  uiff: uiff(P;Q),  and: P ∧ Q,  exists: ∃x:A. B[x],  prop: ℙ,  or: P ∨ Q,  sq_type: SQType(T),  guard: {T},  bnot: ¬bb,  assert: ↑b,  false: False,  not: ¬A,  so_lambda: λ2x y.t[x; y],  so_apply: x[s1;s2]

Latex:
\mforall{}[A,B:Type].  \mforall{}[X:hdataflow(A;B  {}\mrightarrow{}  bag(B))].  \mforall{}[bs:bag(B)].
    hdf-buffer(X;bs)  \mmember{}  hdataflow(A;B)  supposing  valueall-type(B)
