Nuprl Lemma : assert-cs-is-committed

[V:Type]. ∀x:consensus-state3(V). (↑cs-is-committed(x) ⇐⇒ ∃v:V. (x COMMITED[v] ∈ consensus-state3(V)))


Proof




Definitions occuring in Statement :  cs-is-committed: cs-is-committed(x) cs-commited: COMMITED[v] consensus-state3: consensus-state3(T) assert: b uall: [x:A]. B[x] all: x:A. B[x] exists: x:A. B[x] iff: ⇐⇒ Q universe: Type equal: t ∈ T
