Proof




Definitions occuring in Statement :  cs-ref-map3: cs-ref-map3(L) consensus-ts3: consensus-ts3(T) cs-commited: COMMITED[v] cs-considering: CONSIDERING[v] consensus-state3: consensus-state3(T) cs-ambivalent: AMBIVALENT consensus-state2: consensus-state2(T) l_member: (x ∈ l) uiff: uiff(P;Q) uall: [x:A]. B[x] not: ¬A and: P ∧ Q universe: Type equal: t ∈ T ts-reachable: ts-reachable(ts)
