Nuprl Lemma : cut-of-property

[Info:Type]. ∀[es:EO+(Info)]. ∀[X:EClass(Top)]. ∀[f:sys-antecedent(es;X)]. ∀[s:fset(E(X))].
  (s ⊆ cut(X;f;s) ∧ (∀[c':Cut(X;f)]. cut(X;f;s) ⊆ c' supposing s ⊆ c'))


Proof




Definitions occuring in Statement :  cut-of: cut(X;f;s) es-cut: Cut(X;f) sys-antecedent: sys-antecedent(es;Sys) es-E-interface: E(X) eclass: EClass(A[eo; e]) event-ordering+: EO+(Info) es-eq: es-eq(es) f-subset: xs ⊆ ys fset: fset(T) uimplies: supposing a uall: [x:A]. B[x] top: Top and: P ∧ Q universe: Type
