Nuprl Lemma : lookup-list-map-isEmpty_wf

∀[Key,Value:Type]. ∀[m:lookup-list-map-type(Key;Value)].  (lookup-list-map-isEmpty(m) ∈ 𝔹)


Proof




Definitions occuring in Statement :  lookup-list-map-isEmpty: lookup-list-map-isEmpty(m),  lookup-list-map-type: lookup-list-map-type(Key;Value),  bool: 𝔹,  uall: ∀[x:A]. B[x],  member: t ∈ T,  universe: Type
Definitions unfolded in proof :  uall: ∀[x:A]. B[x],  member: t ∈ T,  lookup-list-map-isEmpty: lookup-list-map-isEmpty(m),  lookup-list-map-type: lookup-list-map-type(Key;Value),  subtype_rel: A ⊆r B,  uimplies: b supposing a,  top: Top

Latex:
\mforall{}[Key,Value:Type].  \mforall{}[m:lookup-list-map-type(Key;Value)].    (lookup-list-map-isEmpty(m)  \mmember{}  \mBbbB{})
