Nuprl Lemma : respects-equality-bag

[A,B:Type].  respects-equality(bag(A);bag(B)) supposing respects-equality(A;B)


Proof




Definitions occuring in Statement :  bag: bag(T) uimplies: supposing a respects-equality: respects-equality(S;T) uall: [x:A]. B[x] universe: Type
Definitions unfolded in proof :  uall: [x:A]. B[x] uimplies: supposing a bag: bag(T) member: t ∈ T so_lambda: λ2y.t[x; y] so_apply: x[s1;s2] all: x:A. B[x] implies:  Q permutation: permutation(T;L1;L2) exists: x:A. B[x] and: P ∧ Q cand: c∧ B prop: respects-equality: respects-equality(S;T) label: ...$L... t guard: {T} surject: Surj(A;B;f) int_seg: {i..j-} lelt: i ≤ j < k decidable: Dec(P) or: P ∨ Q not: ¬A satisfiable_int_formula: satisfiable_int_formula(fmla) false: False top: Top subtype_rel: A ⊆B so_lambda: λ2x.t[x] so_apply: x[s] sq_type: SQType(T) true: True squash: T iff: ⇐⇒ Q permute_list: (L f)
