Nuprl Lemma : prefix-replace_wf
∀[t,x:Name]. ∀[pre:pi_prefix()]. (prefix-replace(t;x;pre) ∈ pi_prefix())
Proof
Definitions occuring in Statement :
prefix-replace: prefix-replace(t;x;pre),
pi_prefix: pi_prefix(),
name: Name,
uall: ∀[x:A]. B[x],
member: t ∈ T
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
prefix-replace: prefix-replace(t;x;pre),
let: let,
so_lambda: λ2x y.t[x; y],
so_apply: x[s1;s2]
Latex:
\mforall{}[t,x:Name]. \mforall{}[pre:pi\_prefix()]. (prefix-replace(t;x;pre) \mmember{} pi\_prefix())
