Nuprl Lemma : lg-map_wf

[T,S:Type]. ∀[f:T ⟶ S]. ∀[g:LabeledGraph(T)].  (lg-map(f;g) ∈ LabeledGraph(S))


Proof




Definitions occuring in Statement :  lg-map: lg-map(f;g) labeled-graph: LabeledGraph(T) uall: [x:A]. B[x] member: t ∈ T function: x:A ⟶ B[x] universe: Type
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T labeled-graph: LabeledGraph(T) subtype_rel: A ⊆B all: x:A. B[x] so_lambda: λ2x.t[x] so_apply: x[s] lg-map: lg-map(f;g) guard: {T} nat: spreadn: spread3 uimplies: supposing a top: Top and: P ∧ Q le: A ≤ B less_than': less_than'(a;b) false: False not: ¬A implies:  Q prop: squash: T true: True iff: ⇐⇒ Q rev_implies:  Q ge: i ≥  decidable: Dec(P) or: P ∨ Q satisfiable_int_formula: satisfiable_int_formula(fmla) exists: x:A. B[x]
