Nuprl Lemma : rec-combined-class1_wf

[Info,A,B:Type]. ∀[F:bag(A) ⟶ bag(B) ⟶ bag(B)]. ∀[X:EClass(A)].  (x,s.F[x;s]|X, Prior(self)| ∈ EClass(B))


Proof




Definitions occuring in Statement :  rec-combined-class1: x,s.F[x; s]|X, Prior(self)| eclass: EClass(A[eo; e]) uall: [x:A]. B[x] so_apply: x[s1;s2] member: t ∈ T function: x:A ⟶ B[x] universe: Type bag: bag(T)
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T rec-combined-class1: x,s.F[x; s]|X, Prior(self)| nat: le: A ≤ B and: P ∧ Q less_than': less_than'(a;b) false: False not: ¬A implies:  Q prop: so_lambda: λ2y.t[x; y] subtype_rel: A ⊆B so_apply: x[s1;s2] int_seg: {i..j-} uimplies: supposing a guard: {T} lelt: i ≤ j < k all: x:A. B[x] decidable: Dec(P) or: P ∨ Q satisfiable_int_formula: satisfiable_int_formula(fmla) exists: x:A. B[x] top: Top less_than: a < b squash: T true: True
