Nuprl Lemma : es-E-interface-co-restrict

[Info,A:Type]. ∀[I:EClass(A)]. ∀[P:es:EO+(Info) ⟶ E ⟶ ℙ]. ∀[p:∀es:EO+(Info). ∀e:E.  Dec(P[es;e])]. ∀[es:EO+(Info)].
  (E((I|¬p)) ⊆E(I))


Proof




Definitions occuring in Statement :  es-interface-co-restrict: (I|¬p) es-E-interface: E(X) eclass: EClass(A[eo; e]) event-ordering+: EO+(Info) es-E: E decidable: Dec(P) subtype_rel: A ⊆B uall: [x:A]. B[x] prop: so_apply: x[s1;s2] all: x:A. B[x] function: x:A ⟶ B[x] universe: Type
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T subtype_rel: A ⊆B so_lambda: λ2y.t[x; y] so_apply: x[s1;s2] uimplies: supposing a all: x:A. B[x] top: Top implies:  Q uiff: uiff(P;Q) and: P ∧ Q prop: so_lambda: λ2x.t[x] so_apply: x[s]
