Nuprl Lemma : zip_cons_nil_lemma
∀b,a:Top. (zip([a / b];[]) ~ [])
Proof
Definitions occuring in Statement :
zip: zip(as;bs),
cons: [a / b],
nil: [],
top: Top,
all: ∀x:A. B[x],
sqequal: s ~ t
Definitions unfolded in proof :
all: ∀x:A. B[x],
member: t ∈ T,
zip: zip(as;bs),
so_lambda: so_lambda(x,y,z.t[x; y; z]),
top: Top,
so_apply: x[s1;s2;s3]
