Nuprl Lemma : eclass1-single-val
∀[Info,B,C:Type]. ∀[X:EClass(B)]. ∀[f:Id ─→ B ─→ C]. ∀[es:EO+(Info)].
single-valued-classrel(es;(f o X);C) supposing single-valued-classrel(es;X;B)
Proof
Definitions occuring in Statement :
eclass1: (f o X),
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],
function: x:A ─→ B[x],
universe: Type
