Nuprl Lemma : class-at-single-val
∀[Info:Type]. ∀[es:EO+(Info)]. ∀[T:Type]. ∀[X:EClass(T)]. ∀[locs:bag(Id)].
single-valued-classrel(es;X@locs;T) supposing single-valued-classrel(es;X;T)
Proof
Definitions occuring in Statement :
class-at: X@locs,
single-valued-classrel: single-valued-classrel(es;X;T),
eclass: EClass(A[eo; e]),
event-ordering+: EO+(Info),
Id: Id,
uimplies: b supposing a,
uall: ∀[x:A]. B[x],
universe: Type,
bag: bag(T)
Definitions unfolded in proof :
single-valued-classrel: single-valued-classrel(es;X;T),
uall: ∀[x:A]. B[x],
member: t ∈ T,
iff: P ⇐⇒ Q,
and: P ∧ Q,
implies: P ⇒ Q,
all: ∀x:A. B[x],
subtype_rel: A ⊆r B,
prop: ℙ,
so_lambda: λ2x.t[x],
so_apply: x[s],
so_lambda: λ2x y.t[x; y],
so_apply: x[s1;s2],
uimplies: b supposing a
