Nuprl Lemma : assert-ses-is-legal

prvt:Atom1. ∀pas:ProtocolAction List.  (↑ses-is-legal(prvt; pas) ⇐⇒ Legal(pas) given prvt)


Proof




Definitions occuring in Statement :  ses-is-legal: ses-is-legal(prvt; pas) ses-legal-sequence: Legal(pas) given prvt protocol-action: ProtocolAction list: List atom: Atom$n assert: b all: x:A. B[x] iff: ⇐⇒ Q
Definitions unfolded in proof :  all: x:A. B[x] ses-is-legal: ses-is-legal(prvt; pas) member: t ∈ T subtype_rel: A ⊆B uall: [x:A]. B[x] so_lambda: λ2x.t[x] so_apply: x[s] prop: implies:  Q decidable: Dec(P) or: P ∨ Q isl: isl(x) assert: b ifthenelse: if then else fi  btrue: tt iff: ⇐⇒ Q and: P ∧ Q rev_implies:  Q true: True bfalse: ff false: False not: ¬A
