Nuprl Lemma : lg-label-map

[f:Top]. ∀[g:LabeledGraph(Top)]. ∀[x:ℕlg-size(g)].  (lg-label(lg-map(f;g);x) lg-label(g;x))


Proof




Definitions occuring in Statement :  lg-map: lg-map(f;g) lg-label: lg-label(g;x) lg-size: lg-size(g) labeled-graph: LabeledGraph(T) int_seg: {i..j-} uall: [x:A]. B[x] top: Top apply: a natural_number: $n sqequal: t
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T labeled-graph: LabeledGraph(T) lg-size: lg-size(g) subtype_rel: A ⊆B nat: all: x:A. B[x] implies:  Q lg-label: lg-label(g;x) lg-map: lg-map(f;g) guard: {T} int_seg: {i..j-} prop: ge: i ≥  lelt: i ≤ j < k and: P ∧ Q decidable: Dec(P) or: P ∨ Q uimplies: supposing a satisfiable_int_formula: satisfiable_int_formula(fmla) exists: x:A. B[x] false: False not: ¬A top: Top select: L[n] nil: [] it: so_lambda: λ2y.t[x; y] so_apply: x[s1;s2] cons: [a b] colength: colength(L) so_lambda: λ2x.t[x] so_apply: x[s] sq_type: SQType(T) less_than: a < b squash: T less_than': less_than'(a;b) spreadn: spread3 bool: 𝔹 unit: Unit btrue: tt uiff: uiff(P;Q) ifthenelse: if then else fi  pi1: fst(t) bfalse: ff bnot: ¬bb assert: b
