Nuprl Lemma : cut-of_wf
∀[Info:Type]. ∀[es:EO+(Info)]. ∀[X:EClass(Top)]. ∀[f:sys-antecedent(es;X)]. ∀[s:fset(E(X))]. (cut(X;f;s) ∈ Cut(X;f))
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),
fset: fset(T),
uall: ∀[x:A]. B[x],
top: Top,
member: t ∈ T,
universe: Type
Definitions unfolded in proof :
pi1: fst(t),
exists: ∃x:A. B[x],
implies: P ⇒ Q,
all: ∀x:A. B[x],
so_apply: x[s],
uimplies: b supposing a,
es-cut: Cut(X;f),
and: P ∧ Q,
prop: ℙ,
so_apply: x[s1;s2],
subtype_rel: A ⊆r B,
so_lambda: λ2x y.t[x; y],
so_lambda: λ2x.t[x],
cut-of: cut(X;f;s),
member: t ∈ T,
uall: ∀[x:A]. B[x]
