{ [a:Atom1]. [d1,d2:SecurityData].  uiff(<d1, d2= data(a);False) }

{ Proof }



Definitions occuring in Statement :  sdata-pair: <d1, d2> atom-sdata: data(a) sdata: SecurityData uiff: uiff(P;Q) uall: [x:A]. B[x] false: False equal: s = t atom: Atom$n
Definitions :  uall: [x:A]. B[x] uiff: uiff(P;Q) false: False member: t  T and: P  Q uimplies: b supposing a prop: implies: P  Q iff: P  Q
Lemmas :  iff_weakening_uiff false_wf atom-sdata-not-pair sdata_wf sdata-pair_wf atom-sdata_wf

\mforall{}[a:Atom1].  \mforall{}[d1,d2:SecurityData].    uiff(<d1,  d2>  =  data(a);False)
