Nuprl Lemma : state-class1-program-wf-hdf
∀[Info,A,B:Type]. ∀[init:Id ⟶ B]. ∀[f:Id ⟶ A ⟶ B ⟶ B]. ∀[pr:Id ⟶ hdataflow(Info;A)].
(state-class1-program(init;f;pr) ∈ Id ⟶ hdataflow(Info;B)) supposing (valueall-type(B) and (↓B))
Proof
Definitions occuring in Statement :
state-class1-program: state-class1-program(init;tr;pr),
hdataflow: hdataflow(A;B),
Id: Id,
valueall-type: valueall-type(T),
uimplies: b supposing a,
uall: ∀[x:A]. B[x],
squash: ↓T,
member: t ∈ T,
function: x:A ⟶ B[x],
universe: Type
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
uimplies: b supposing a,
state-class1-program: state-class1-program(init;tr;pr),
squash: ↓T,
all: ∀x:A. B[x],
so_lambda: λ2x.t[x],
so_apply: x[s],
exists: ∃x:A. B[x],
prop: ℙ
