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),

eclass: EClass(A[eo; e]),
event-ordering+: EO+(Info),
es-eq: es-eq(es),
f-subset: xs ⊆ ys,
fset: fset(T),
uimplies: b supposing a,
uall: ∀[x:A]. B[x],
top: Top,
universe: Type
