Nuprl Lemma : cut-subset-cut

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


Proof




Definitions occuring in Statement :  cut-of: cut(X;f;s) 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 universe: Type
Definitions unfolded in proof :  so_apply: x[s1;s2] so_lambda: λ2y.t[x; y] prop: implies:  Q es-cut: Cut(X;f) subtype_rel: A ⊆B all: x:A. B[x] f-subset: xs ⊆ ys and: P ∧ Q uimplies: supposing a member: t ∈ T uall: [x:A]. B[x]
