Nuprl Lemma : threshold_val_wf

∀[S,A:Type]. ∀[p:S × (A?)].  (threshold_val(p) ∈ A?)


Proof




Definitions occuring in Statement :  threshold_val: threshold_val(p),  uall: ∀[x:A]. B[x],  unit: Unit,  member: t ∈ T,  product: x:A × B[x],  union: left + right,  universe: Type
Lemmas :  unit_wf2
\mforall{}[S,A:Type].  \mforall{}[p:S  \mtimes{}  (A?)].    (threshold\_val(p)  \mmember{}  A?)
