Nuprl Lemma : return-class-val

[Info:Type]. ∀[x:Top]. ∀[es:EO+(Info)]. ∀[e:E].  return-class(x)(e) supposing ↑e ∈b return-class(x)


Proof




Definitions occuring in Statement :  return-class: return-class(x) eclass-val: X(e) in-eclass: e ∈b X event-ordering+: EO+(Info) es-E: E assert: b uimplies: supposing a uall: [x:A]. B[x] top: Top universe: Type sqequal: t
