Nuprl Lemma : consensus-state2-cases

[V:Type]
  ∀x:consensus-state2(V)
    ((x AMBIVALENT ∈ consensus-state2(V))
    ∨ (∃v:V. ((x PREDECIDED[v] ∈ consensus-state2(V)) ∨ (x Decided[v] ∈ consensus-state2(V)))))


Proof




Definitions occuring in Statement :  cs-predecided: PREDECIDED[v] cs-ambivalent: AMBIVALENT consensus-state2: consensus-state2(T) cs-decided: Decided[v] uall: [x:A]. B[x] all: x:A. B[x] exists: x:A. B[x] or: P ∨ Q universe: Type equal: t ∈ T
