Nuprl Lemma : name-morph-flip-face-map

I:Cname List. ∀y:nameset(I). ∀a:ℕ2. ∀c1:name-morph(I;[]). ∀v:nameset(I).
  ((¬(v y ∈ Cname))  (flip(((y:=a) c1);v) ((y:=a) flip(c1;v)) ∈ name-morph(I;[])))


Proof




Definitions occuring in Statement :  name-morph-flip: flip(f;y) name-comp: (f g) face-map: (x:=i) name-morph: name-morph(I;J) nameset: nameset(L) coordinate_name: Cname nil: [] list: List int_seg: {i..j-} all: x:A. B[x] not: ¬A implies:  Q natural_number: $n equal: t ∈ T
