Nuprl Lemma : es-opt-prior-val_wf
∀[Info,T:Type]. ∀[d:T]. ∀[es:EO+(Info)]. ∀[X:EClass(T)]. ∀[e:E]. (X'(e)?d ∈ T)
Proof
Definitions occuring in Statement :
es-opt-prior-val: X'(e)?d,
eclass: EClass(A[eo; e]),
event-ordering+: EO+(Info),
es-E: E,
uall: ∀[x:A]. B[x],
member: t ∈ T,
universe: Type
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
es-opt-prior-val: X'(e)?d,
subtype_rel: A ⊆r B,
so_lambda: λ2x y.t[x; y],
so_apply: x[s1;s2],
uimplies: b supposing a,
all: ∀x:A. B[x],
top: Top,
implies: P ⇒ Q,
bool: 𝔹,
unit: Unit,
it: ⋅,
btrue: tt,
uiff: uiff(P;Q),
and: P ∧ Q,
ifthenelse: if b then t else f fi ,
bfalse: ff,
es-E-interface: E(X)
