Nuprl Lemma : select-indices-aux_wf

[A:Type]. ∀[f:A ⟶ 𝔹]. ∀[L:A List].  (select-indices-aux(f;L) ∈ ℕ ⟶ (ℕ List))


Proof




Definitions occuring in Statement :  select-indices-aux: select-indices-aux(f;L) list: List nat: bool: 𝔹 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 all: x:A. B[x] nat: implies:  Q false: False ge: i ≥  uimplies: supposing a satisfiable_int_formula: satisfiable_int_formula(fmla) exists: x:A. B[x] not: ¬A top: Top and: P ∧ Q prop: subtype_rel: A ⊆B or: P ∨ Q cons: [a b] colength: colength(L) so_lambda: λ2y.t[x; y] so_apply: x[s1;s2] guard: {T} decidable: Dec(P) nil: [] it: 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) select-indices-aux: select-indices-aux(f;L) so_lambda: so_lambda(x,y,z.t[x; y; z]) so_apply: x[s1;s2;s3] bool: 𝔹 unit: Unit btrue: tt ifthenelse: if then else fi  uiff: uiff(P;Q) bfalse: ff bnot: ¬bb assert: b
