Nuprl Lemma : assert-in-missing

∀i:ℤ. ∀missing:ℤ List.  ((↑in-missing(i;missing)) ⇒ (i ∈ missing))


Proof




Definitions occuring in Statement :  in-missing: in-missing(i;missing),  l_member: (x ∈ l),  list: T List,  assert: ↑b,  all: ∀x:A. B[x],  implies: P ⇒ Q,  int: ℤ
Definitions unfolded in proof :  all: ∀x:A. B[x],  uall: ∀[x:A]. B[x],  member: t ∈ T,  so_lambda: λ2x.t[x],  implies: P ⇒ Q,  prop: ℙ,  so_apply: x[s],  false: False,  assert: ↑b,  ifthenelse: if b then t else f fi ,  in-missing: in-missing(i;missing),  reduce: reduce(f;k;as),  list_ind: list_ind,  nil: [],  it: ⋅,  bfalse: ff,  iff: P ⇐⇒ Q,  and: P ∧ Q,  rev_implies: P ⇐ Q,  top: Top,  uiff: uiff(P;Q),  uimplies: b supposing a,  or: P ∨ Q,  guard: {T}
