Nuprl Lemma : parallel-class-disjoint-classrel
∀[Info,A,B:Type]. ∀[es:EO+(Info)]. ∀[X,Y:EClass(A)]. ∀[Z:EClass(B)].
  (disjoint-classrel(es;A;X;B;Z) 
⇒ disjoint-classrel(es;A;Y;B;Z) 
⇒ disjoint-classrel(es;A;X || Y;B;Z))
Proof
Definitions occuring in Statement : 
parallel-class: X || Y
,

, 
event-ordering+: EO+(Info)
, 
uall: ∀[x:A]. B[x]
, 
implies: P 
⇒ Q
