Nuprl Lemma : class-caused-by_wf
∀[f:Name ⟶ Type]. ∀[es:EO+(Message(f))]. ∀[Z:EClass(Id × Message(f))]. ∀[T:Type]. ∀[X:EClass(T)]. (X <-- Z ∈ ℙ')
Proof
Definitions occuring in Statement :
class-caused-by: X <-- Z,
Message: Message(f),
eclass: EClass(A[eo; e]),
event-ordering+: EO+(Info),
Id: Id,
name: Name,
uall: ∀[x:A]. B[x],
prop: ℙ,
member: t ∈ T,
function: x:A ⟶ B[x],
product: x:A × B[x],
universe: Type
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
class-caused-by: X <-- Z,
subtype_rel: A ⊆r B,
so_lambda: λ2x.t[x],
implies: P ⇒ Q,
prop: ℙ,
and: P ∧ Q,
so_apply: x[s],
exists: ∃x:A. B[x],
uimplies: b supposing a,
all: ∀x:A. B[x],
label: ...$L... t
