Nuprl Lemma : RankEx2_size_wf
∀[S,T:Type]. ∀[p:RankEx2(S;T)]. (RankEx2_size(p) ∈ ℕ)
Proof
Definitions occuring in Statement :
RankEx2_size: RankEx2_size(p),
RankEx2: RankEx2(S;T),
nat: ℕ,
uall: ∀[x:A]. B[x],
member: t ∈ T,
universe: Type
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
RankEx2_size: RankEx2_size(p),
RankEx2co_size: RankEx2co_size(p),
RankEx2: RankEx2(S;T),
uimplies: b supposing a,
nat: ℕ,
so_lambda: λ2x.t[x],
so_apply: x[s]
