{ [A:Id List]. [W:{a:Id| (a  A)}  List List].  (three-intersection(A;W)  ) \000C}

{ Proof }



Definitions occuring in Statement :  three-intersection: three-intersection(A;W) Id: Id uall: [x:A]. B[x] prop: member: t  T set: {x:A| B[x]}  list: type List l_member: (x  l)
Definitions :  uall: [x:A]. B[x] member: t  T prop: three-intersection: three-intersection(A;W) exists: x:A. B[x] and: P  Q so_lambda: x.t[x] so_apply: x[s]
Lemmas :  l_all_wf2 l_member_wf Id_wf

\mforall{}[A:Id  List].  \mforall{}[W:\{a:Id|  (a  \mmember{}  A)\}    List  List].    (three-intersection(A;W)  \mmember{}  \mBbbP{})
