Nuprl Lemma : bm_delete'_wf

∀[T,Key:Type]. ∀[m1,m2:binary-map(T;Key)].  (bm_delete'(m1;m2) ∈ binary-map(T;Key))


Proof




Definitions occuring in Statement :  bm_delete': bm_delete'(m1;m2),  binary-map: binary-map(T;Key),  uall: ∀[x:A]. B[x],  member: t ∈ T,  universe: Type
Definitions unfolded in proof :  uall: ∀[x:A]. B[x],  member: t ∈ T,  bm_delete': bm_delete'(m1;m2),  binary-map: binary-map(T;Key),  ext-eq: A ≡ B,  and: P ∧ Q,  subtype_rel: A ⊆r B,  all: ∀x:A. B[x],  implies: P ⇒ Q,  bool: 𝔹,  unit: Unit,  it: ⋅,  btrue: tt,  uiff: uiff(P;Q),  uimplies: b supposing a,  sq_type: SQType(T),  guard: {T},  eq_atom: x =a y,  ifthenelse: if b then t else f fi ,  bm_E: bm_E(),  assert: ↑b,  top: Top,  so_lambda: so_lambda(x,y,z,w,v.t[x; y; z; w; v]),  so_apply: x[s1;s2;s3;s4;s5],  bfalse: ff,  exists: ∃x:A. B[x],  prop: ℙ,  or: P ∨ Q,  bnot: ¬bb,  false: False,  bm_T: bm_T(key;value;cnt;left;right),  bm_T?: bm_T?(v),  pi1: fst(t),  true: True
