Nuprl Lemma : simple-comb-2_wf

[Info,A,B,C:Type].  ∀F:bag(A) ⟶ bag(B) ⟶ bag(C). ∀[X:EClass(A)]. ∀[Y:EClass(B)].  (F|X, Y| ∈ EClass(C))


Proof




Definitions occuring in Statement :  simple-comb-2: F|X, Y| eclass: EClass(A[eo; e]) uall: [x:A]. B[x] all: x:A. B[x] 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 all: x:A. B[x] simple-comb-2: F|X, Y| nat: le: A ≤ B and: P ∧ Q less_than': less_than'(a;b) false: False not: ¬A implies:  Q prop: int_seg: {i..j-} uimplies: supposing a guard: {T} lelt: i ≤ j < k decidable: Dec(P) or: P ∨ Q satisfiable_int_formula: satisfiable_int_formula(fmla) exists: x:A. B[x] top: Top sq_type: SQType(T) select: L[n] cons: [a b] subtract: m less_than: a < b squash: T true: True subtype_rel: A ⊆B so_lambda: λ2y.t[x; y] so_apply: x[s1;s2]
