Nuprl Lemma : map-class_wf

[Info,A,B:Type]. ∀[f:A ⟶ B]. ∀[X:EClass(A)].  ((f[v] where from X) ∈ EClass(B))


Proof




Definitions occuring in Statement :  map-class: (f[v] where from X) eclass: EClass(A[eo; e]) uall: [x:A]. B[x] so_apply: x[s] member: t ∈ T function: x:A ⟶ B[x] universe: Type
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T map-class: (f[v] where from X) all: x:A. B[x] so_apply: x[s] so_lambda: λ2y.t[x; y] subtype_rel: A ⊆B so_apply: x[s1;s2]

Latex:
\mforall{}[Info,A,B:Type].  \mforall{}[f:A  {}\mrightarrow{}  B].  \mforall{}[X:EClass(A)].    ((f[v]  where  v  from  X)  \mmember{}  EClass(B))
