Nuprl Lemma : parallel-classrel
∀[T,Info:Type]. ∀[X,Y:EClass(T)]. ∀[es:EO+(Info)]. ∀[e:E]. ∀[v:T]. uiff(v ∈ X || Y(e);v ∈ X(e) ↓∨ v ∈ Y(e))
Proof
Definitions occuring in Statement :
parallel-class: X || Y,
classrel: v ∈ X(e),
eclass: EClass(A[eo; e]),
event-ordering+: EO+(Info),
es-E: E,
sq_or: a ↓∨ b,
uiff: uiff(P;Q),
uall: ∀[x:A]. B[x],
universe: Type
Definitions unfolded in proof :
sq_or: a ↓∨ b,
uall: ∀[x:A]. B[x],
member: t ∈ T,
uiff: uiff(P;Q),
and: P ∧ Q,
uimplies: b supposing a,
squash: ↓T,
prop: ℙ,
classrel: v ∈ X(e),
bag-member: x ↓∈ bs,
subtype_rel: A ⊆r B,
so_lambda: λ2x y.t[x; y],
so_apply: x[s1;s2],
parallel-class: X || Y,
eclass-compose2: eclass-compose2(f;X;Y),
all: ∀x:A. B[x],
eclass: EClass(A[eo; e]),
iff: P ⇐⇒ Q,
implies: P ⇒ Q,
rev_implies: P ⇐ Q
